The invention relates to a radar inter-station link communication technology, and especially relates to a radar inter-station low-jitter anti-interference signal communication link technology based on an OFDM technology and an LMS algorithm. Through combination of characteristics of the high multi-path interference resistance capability of the OFDM technology and the high noise suppression capability of an LMS, low jitter and interference resistance between radar stations can be achieved. A signal and a training sequence are simultaneously send through IQ modulation in a same-frequency manner; and, compared with the prior art that a block-type pilot frequency and a comb-type pilot frequency are usually adopted to perform channel estimation, the technology can be better adapted to a quick-change and fixed-frequency interference channel.
