【摘要】 研究了GPS卫星作为照射源 ,接收机在地面的天地收发分置的双基地雷达探测系统。该系统通过测量目标双基地距离和与目标双基地多普勒频率来实现对目标的探测。通过对回波信号进行多普勒补偿之后再进行相干积累和非相干积累 ,获得较大的处理增益 ,从而实现对微弱目标信号的检测。更多还原

【Abstract】 The GPS satellite as illumination sources, a bistatic radar system with the receiver on the ground is investigated. The objects can be detected by this radar system through measuring the bistatic range sum and bistatic doppler frequency. To detect the weak signal from objects, a method to increase processing gain is proposed using doppler frequency compensation coherent integration and non-coherent integration.更多还原
