random binary phase coded pulse radar%noise radar%radar signal processing%pulse compression
The application of the random binary phase coded signal in the CW radar system has been limited by the difficulty to isolate the tranmission and reception signal. In order to make use of the random binary phase coded signal, the random binary phase coded pulse radar (RBPC-PR) system has been studied. First, the average ambiguity function (AAF) of the RBPC-PR signal has been analyzed. Then, a statistical method of reducing the range sidelobe (RSL) is presented. Finally, a signal processing scheme of the RBPC-PR is developed. The simulation results show that by using the scheme, the jamming immunity of the system, the resolution and accuracy of distance and velocity have been improved, and the distance and velocity vagueness caused by periods can also be removed. The RSL can be reduced over 30dB by the statistical average method, thus the probability ambiguity caused by random noise can be avoided.
