Outline of Final Research Achievements

This research is the basic research for the next-generation automotive radar. In this research, the conventional mono-static radar was developed to multi-static (MIMO) radar as the measurement method. At first, initial simulation and experiments of bi-static radar were conducted before considering multi-static radar. In the first step, mitigation of the ambiguity generated in multilateration by combining a tracking filter was proposed. On the other hand, estimation method for two dimensional velocity and positional vectors are also considered by mono-static multiple frequency step CPC radar. The initial experimental results indicated that the estimation method works for the targets having rigid bodies. Then, I expanded the mono-static radar to the multi-static (MIMO) radar using multiple frequency step CPC and Phase Coded High Pulse Repetition (PC-HPRF) modulations. The effectiveness was also indicated by simulation. The experimental verifications are the future work.
