Abstract

An interference suppression method based on joint fractional Fourier domain and time domain is proposed in this paper, to solve the problem of co-channel interference caused by homo-type radars working in ship formation. The interferences with different chirp rate from echo signal can be eliminated at fractional Fourier domain, and because of the reversibility of fractional Fourier transform, the ones with similar chirp rate can be cancelled by against-asynchronism of adjacent periods at time domain. Computer simulation results show that interference suppression processing gain reaches 29 dB. This method presents technical support for the ElectroMagnetic Compatibility (EMC) research in the ship formation.
