Abstract:
In this paper, with the help of the nonlinear target detection and classification, we have developed a new automotive radar concept. The nonlinear products of the transmitter signals and harmonic and intermodulation of the third-order are detected by the harmonic radar are carried by the target carriers of the nonlinear tag. The reflection works to detect the cares of the second harmonics of the radar transmitter signals - two LFM modulated carriers, whereas
the vulnerable targets, such as pedestrians, children and similar, are detected by reflection of the third-order intermodulation products. The nonlinear transfer character works to generate the intermodulation products by the power amplifier in the radar transmitter. The second harmonic of the transmitted signals exploit the linearization techniques.
