The conventional auxiliary channel receiver method is limited by the prior knowledge of clutter distribution and system error in practical application, thus inducing mismatch between the selected auxiliary channels and actual clutter distribution. To deal with the problem, based on least-square parameter estimation, an adaptive space-time auxiliary channel receiver method is proposed in this paper. Firstly, a space-time snapshot of a single range cell is used to estimate the clutter distribution and system parameters are estimated via the least-square method. Then the auxiliary channels are selected adaptively to carry out reduced-dimension adaptive space-time processing. With snapshots from a single range bin, parameter estimation can be achieved with better accuracy. Besides, the proposed method is applicable to arbitrary array geometries, and therefore it is a flexible and robust implementation. Simulation results demonstrate the effectiveness of the proposed method.
