Abstract
The accumulation and detection of space partial-coherent echoes is a difficult problem in jointly signal processing for distributed radar. Traditional coherent and incoherent accumulation and detection methods have a performance loss when echoes are partial-coherent. For this problem,a three-dimensional target scattering model is presented and the change rule of echoes spatial correlation is analyzed. Then,a time-domain weighed power detector is employed to space partial-coherent accumulation and detection. Fi-nally,an accumulation and detection method of adaptive selection based on the value of spatial correlation coefficient is proposed,and the problem of accumulation and detection with arbitrarily correlation is solved. The simulation results show that the method can choose three accumulation and detection methods accord-ing to the value of correlation coefficient correctly,and the detection performance is superior to that of tradi-tional coherent and incoherent methods.关键词
