The passive detection system based on FM broadcasting has many advantages such as anti stealth and anti-interference.However,due to the special nature of the system,it is extremely susceptible to interference from other same frequency radio stations,which seriously affects the system performance.In response to this situation,the article proposes a blind source separation co frequency interference suppression method based on time smooth second-order covariance matrix decomposition.The simulation results show that the algorithm still has good robustness even when the interference to signal ratio is very high.
