Abstract:

In this paper, the spatial resolution limit for ultrawideband (UWB) MIMO noise radar is presented based on the statistical resolution theory. The signal model of UWB MIMO noise radar is established, and the resolution of two closely spaced targets is modeled as a binary hypothesis test. The statistical spatial resolution limit (SSRL) for UWB MIMO noise radar is derived based on the generalized likelihood ratio test (GLRT) with the constraints on the probabilities of false alarm and detection. The effects of detection parameters, transmit waveforms, array geometry, signal-to-noise ratio (SNR) and parameters of target on the SSRL are analyzed. Compared with the conventional resolution defined by ambiguity function, the SSRL reflects the practical resolution ability of radar and can provide an optimization criterion for radar system design.
