Missile-borne Near-field Radar Coincidence Imaging Using a Uniform Circular Array

near-field; radar coincidence imaging (RCI); uniform circular array (UCA)

A near-field radar coincidence imaging (NFRCI) method is proposed in this paper, which can work in forward-looking mode and also achieve fast imaging in missile-borne radar imaging system. Using a uniform circular array (UCA) as the transmitting antenna of missile-borne radar, every element of the UCA transmits random phase modulation (RPM) signals. Based on sparse parametric model and sparse Bayesian learning (SBL) algorithm, the image of NFRCI is obtained. Simulations are presented to validate the effectiveness of the proposed method.
