In the transmission process of 1090ES ADS-B signal, it is easy to see the relationship between signal overlap and signal interference. The signal noise under interference easily causes the error of ADS-B signal decoding. In this paper, a 1090ES ADS-B signal separation algorithm based on PCA and FastICA is designed to achieve the separation of ADS-B signals and the separation of overlapped signals. Through simulation and verification, the 1090ES ADS-B signal separation algorithm based on PCA and ICA can realize the denoising and separation of ADS-B signal and reduce the computation and speed of separation. The signal reduction degree after separation is relatively high.
