摘要：
An imaging method that uses the distributed apertures for passive radar imaging of moving targets is presented. First of all, we present the signal model of the moving targets, which does not require any information of the transmitting sources. Then, due to the limited number of received signals obtained via the distributed apertures, we formulate the imaging problem as a generalized likelihood ratio test (GLRT) with unknown target position and velocity and complete the target imaging and velocity estimation by applying the GLRT at each possible position and velocity. Finally, we perform simulations using the worldwide interoperability for microwave access (WiMAX) signals as an illuminator of opportunity and demonstrate the effectiveness of the proposed method. ©, 2015, Chinese Institute of Electronics.
