宽带雷达动目标的一种互相关系数累加检测器
Correlation-coefficient-summation detector for wideband radar moving targets
摘要
Abstract
A correlation coefficient summation detector under the Gaussian noise for wideband radar moving targets are presented.Fourier transformation is carried out to take the absolute value for the signals of wideband radar moving targets in the range-frequency domain in order to remove the phase item caused by target moving,and then the correlation coefficient of conjoint signals are computed.By the property that the conjoint range spread target signals possess a high relativity,the summation of correlation coefficients is used for detect.After analyzing the probability of the echo signal without targets under the Gaussian noise, the detect threshold setting of the correlation coefficient summation detector is given and theoretical analysis shows that the detector possesses constant false alarm rate (CFAR) performance.Computer simulation shows that the correlation coefficient summation detector given in this paper can achieve 2 dB performance improvement than the non-scatterer density dependent generalized likelihood ratio test (NSDD-GLRT) detector with the known Doppler steering vector at the 90% detection.关键词
