In the presence of sensor gain and phase uncertainties for sensor array, the problem of high-resolution estimation of DOA-Doppler frequency for multiple targets signals is addressed. Making use of rotational invariance technique and collecting data of targets signals at two known carrier frequencies, the proposed method in this paper can estimate DOA-Doppler frequency of multiple targets accurately. Simultaneously, sensor gain and phase factors can be estimated precisely, then the manifold of sensor array can be calibrated in the following step. Simulation and practical example results illustrate that this method has superior performance.
