Abstract

In the presence of sensor gain and phase uncertainties for sensor array, this paper addressed the problem of High-resolution estimation of DOA-Doppler frequency for multiple signals. By utilizing rotational invariance technique and collecting data of signals at two different carrier frequencies, the proposed method can precisely estimate DOA-Doppler frequency of multiple signals and sensor gain and phase factors. Simulation results illustrate that this method has superior performance.
