摘要：
In this paper, to solve the problem of co-channel interference caused by homo-type radars working in ship formation, an interference suppression method based on joint fractional Fourier domain and time domain is proposed. The interference with different modulated frequency rates from echo signal can be eliminated at fractional Fourier domain and the ones with similar modulated frequency rate can be cancelled at time domain. Computer simulation results show that interference suppression processing gain reaches 29dB. This method can present technical support for the electromagnetic compatibility (EMC) research in the ship formation
