Research on key tchnologies for collision avoidance automotive radar

Anti-interference capability and low cost play decisive roles for the break-through on the market of collision avoidance automotive radar.With the increasing use of automotive radar, the mutual interference becomes an issue. This paper proposes a novel signal design and signal processing methods for automotive radar, which combine good anti-interference capacity and the low cost of conventional frequency modulated continuous wave (FMCW) radar. The radar signal is easy to be generated and its signal processing can be performed by Fast Fourier Transform (FFT) algorithm. So, the proposed new methods is feasible and effective.
