A new all-passive detection method based on the target microwave thermal radiation signal and spatial spectrum estimation is proposed. This method uses spatial spectral estimation to achieve super-resolution, and uses sparse arrangement to reduce the required number of elements. The experimental results show that the target detection method is feasible and the target super-resolution detection is achieved.
