  • This paper proposes an non-cooperative target imaging technique based on the distributed multi-channel radar system, which consists of multiple sparsely-located transmitters and receivers. By coherently processing the signals received in multiple radar channels, the wave-number samples in a plane are obtained, from which the two-dimensional reflectivity function of target is reconstructed. Due to the simultaneous formation of multi-channel echo data and coherent processing of a single snap, it does not require large antennas, and the complicated motion compensation performed in ISAR imaging is not needed. Meanwhile, the reconstructed images are naturally scaled because the sampling locations in wave-number space are known. To validate the imaging performance, the distributed radar systems with wide-band transmitted signal are designed respectively, and the simulations are demonstrated.
