MOSARIM No.2482312012-12-21The EU-funded research project MOSARIMGeneral overview and description of work carried outAbstract: The European funding project MOSARIM (MOre Safety for All by RadarInterference Mitigation) started in January 2010 with the objective to investigate possibleautomotive radar interference mechanisms by both simulation and real-world road-tests.Appropriate countermeasure and mitigation techniques were investigated and assessed andgeneral guidelines and recommendations developed. With a special norm interferer device thatwas also developed during project runtime the mitigation methods could be analyzed andverified in a reproducible and general manner. Project content and results were disseminated intwo international public workshops and via the MOSARIM public webpage.1. IntroductionThe MOSARIM project with Grant Agreement No. 248231 started officially on January 1st,2010. The project duration is 36 month and the total project budget is 4.820.693 with2.897.173 funding.The MOSARIM project’s main objectives are the investigation of mutual vehicular radarinterference and the definition and elaboration of effective countermeasures and mitigationtechniques. Automotive radar operational frequencies from 24 GHz to 79 GHz are coveredby this project.The concept and overall objectives of the MOSARIM project are: on actual radar interference potential and impact with of-the-shelf radarsensors already available on the market.Specification and implementation of a vehicular norm radar interferer.Elaborate comprehensive and realistic simulation models regarding radar interferenceon different levels.Find common applicable interference countermeasures to reduce mutual radarinterference disturbance.Generation of recommendations and guidelines for vehicular mutual radar interferencemitigation.The MOSARIM consortium consists of the following partners (see Figure 1):Figure 1: The MOSARIM consortium with all 12 partnersFile: report final.doc4/21

Each of the tasks is either finished with a deliverable or amilestone, respectively. Most of the delivered documents are public available on theMOSARIM webpage and only reports with sensor-individual, critical information contentwere left confidential. The work package structure is sketched in Figure 3.Figure 3: The MOSARIM project structure (PERT diagram)File: report final.doc5/21

MOSARIM No.2482312012-12-212. The project activitiesWithin the MOSARIM project different topics were addressed with different instruments,mainly simulation tools and real world test campaigns, complemented by studies and scenariodefinitions. While the project was mainly focused on mutual radar interference, i.e. theinterference that occurs among the radars installed on vehicles on the road, in one task alsothe interference from incumbent radar systems, i.e. other non-automotive radars like e.g.police radar, fixed service links or traffic monitoring systems, was addressed. By jointlydeveloping and improving the two main working axes the final project goals and targets couldbe reached.

The already existing advanced driver assistance (ADAS) functions aredepicted in Figure 5.Figure 5: The current ADAS portfolioThe MOSARIM consortium selected the following 8 functions as the principal use cases forfurther evaluation in the real world test campaigns and the according simulations:File: report final.doc6/21

These scenarios were used to define the operational parametersfor the road test campaigns and the respective simulation runs. Figure 6 shows a few samplestaken out of the scenario catalogue.Figure 6: Some scenarios from the catalogue2.3 Market penetration studyIn the project planning phase it was assumed that the density of radars on the road will play animportant role when calculating the maximum interference power. To verify this effect inTask 1.6 the market penetration of radars over time was studied to get first indications aboutthe possible proliferations of radars in the next years. Based on three available market studiesFile: report final.doc7/21

MOSARIM No.2482312012-12-212.4 The radar norm interferer deviceBased on a specification of the parameter sets of the commercially used modulation forms,which were compiled at the beginning of the project, two norm interferer prototypes weredeveloped and used in the laboratory and road test campaigns as replacement of the earlierused individual radar interferer devices from the different radar manufacturers.The basic idea to use a universal norm interferer device is to improve reliability andreproducibility of the interference measurements. Different to the case where speciallyprepared of-the-shelf radar sensors are used as interferers, the norm interferer prototype iscapable to emulate all the existing radar sensor transmission waveforms in an exact timelyand frequency-accurate manner. By software means the different modulation forms can beswitched, making a direct comparison of the interference impact from different modulationwaveforms first possible, as no equipment has to be changed and test-setup is untouched.In Figure 9 the concept of the norm interferer prototype and the used frequency bands isshown. In Figure 10 the final prototype and the supported waveforms are presented.Portable, configurable and free running radar signal transmitting device forarbitrary interference and qualifying testsPCNorm InterfererpowerUSB-Bus21.6523.6 24.0526.657681Frequency [GHz]Figure 9: Norm Interferer prototype with operational frequency rangesNorm Interferer devicein operationNorm Interferer devicesupported waveforms21.65 – 26.65 GHzoutput76-81 GHz outputFigure 10: Norm Interferer prototype and modulation waveformsFile: report final.doc9/21

MOSARIM No.2482312012-12-21From the first tests and measurements done with the two Norm Interferer (NI) prototypes, thebenefit and advantages when using these two NIs became obvious. The results are betterreproducible and measurement time is cut down significantly because no change in setup hasto be done when changing from one sensor modulation scheme to another.For qualifying tests according to a radar interference mitigation standard (that is not yetdefined), the NIs can play a major role. Ideas for commercialization will be driven by thecompany InnoSenT, the project partner who has build-up the two prototypes.2.5 The radar simulation tool-chainThe development of a complete simulation tool-chain was the second main pillar of theMOSARIM project besides the practical assessment of radar interference impact andcountermeasure effectiveness.Based on already existing ray-tracing software for communication channel simulation, anautomotive radar radio-location simulation tool with interference effect simulation was furtherdeveloped by the Karlsruhe Institute of Technology (KIT).The coarse system modelling concept is sketched in Figure 11.Victim timedomain signalTXInterferer timedomain signal (s)TXCan be simplified/replaced if modulationscheme interaction behavior is knownSystem ModellingPath informations- Path loss- Time delay- Doppler shift- Angles of incomingand outgoing wavesChannel modellingRay-tracingsimulationScenarioKnown object positions/velocitiesAnalog signal processingADC & raw data processingDetected objectpositions/velocitiesInterference assessment(I/N, S/I, S/(I N), power distribution in FFT)ComparisonDetermination of system performanceFigure 11: System modelling simulation basics and conceptThe complete road scenario with both static and dynamic traffic scenario simulation ismapped into the simulation framework.
