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

摘要

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 unsufficient 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.
