Abstract

The invention discloses a secondary quantization method of a satellite-borne receiver and the satellite-borne receiver, aiming at the defects of a time domain anti-interference technology, amplitude amplification is carried out on a baseband signal subjected to down-conversion, and then a high order is intercepted, so that the secondary quantization method can adapt to the stability of anti-interference in a large dynamic range; meanwhile, the method ingeniously and effectively suppresses the pulse interference while suppressing the continuous wave interference, is a zero-resource-consumption method for the pulse interference, is low in cost and easy to implement, and can effectively solve the problems of useful signal loss, large resource consumption and complex logic judgment caused by a time domain anti-interference technology.

Description

technical field [0001] The invention relates to the technical field of satellite-borne signal processing, in particular to a secondary quantization method of a satellite-borne receiver and the satellite-borne receiver thereof. Background technique [0002] The increasing complexity of the space electromagnetic environment makes interference more and more complex, and the stability and reliability of spaceborne receivers are seriously affected. In order to suppress various interferences, the anti-jamming technology of spaceborne receivers continues to develop. For the time-domain anti-jamming technology, especially when pulse interference and continuous wave interference exist at the same time, the time-domain narrowband interference suppression technology includes two methods: linear and nonlinear, both of which are based on adaptive filtering and subspace decomposition. CW has a good suppression effect, but it has little effect on pulse interference due to the long converge...
