Abstract:

In view of the single antenna FMCW radar transmitter signal leakage,this article proposes a digital cancellation technology combining with the advantages of the digital adaptive system such as good data processing capability,accuracy,flexibility and universality.Simulation and experiment results shows that the program can effectively suppress the emission signal leakage problems caused by inadequate transceiver isolation.

Key words: digital cancellation;adaptive;signal leakage
