Spatial average ambiguity function for array radar with stochastic signals

For analyzing the spatial resolving performance of multi-transmitter single-receiver (MTSR) array radar with stochastic signals, the spatial average ambiguity function (SAAF) is introduced based on the statistical average theory. The analytic expression of SAAF and the corresponding resolutions in vertical range and in horizontal range are derived. Since spatial resolving performance is impacted by many parameters including signal modulation schemes, signal bandwidth, array aperture’s size and target’s spatial position, comparisons are implemented to analyze these influences. Simulation results are presented to validate the whole analysis.
