Investigation on adaptive leakage nulling for pseudo-random code CW radar

There are many application examples for pseudo-random code (PRC) CW radar used in near distance monitoring, and the spread spectrum characteristic of pseudo-random code makes the radar with LPI feature. But the un-sufficient isolation between the transmitter and receiver of CW radar limits PRC radar form further application in middle range monitoring, based on the analysis existing leakage cancelling technique, a new leakage nulling method for PRC CW radar is presented in this paper. And the test results are promising.
