The velocity vagueness and probability ambiguity remove of the random binary phase coded pulse signal radar

This paper presents a signal processing method to remove the velocity vagueness and probability ambiguity of the random binary phase coded pulse signal (RBPC-PS) radar. From all the results analysed and discussed, we can conclude that because of the excellent specific property of the random signal and by adopting a reasonable signal processing scheme, the RBPC-PS radar system possesses a good resolution and accuracy in measuring the distance and the velocity of the target and good jamming immunity, and it can remove the distance and velocity vagueness caused by periods and extend the Doppler tolerance. From the results we can also see that the statistical method of the range sidelobe (RSL) suppression can reduce the RSL by over 30 dB thus avoiding the probability ambiguity, which makes the RBPC-PS radar system practical
