A framework for the analysisof spatially coherent and incoherent multistatic radar systems

In conventional radar systems, Woodward´s ambiguity function is used to characterize waveform resolution performance. It has been demonstrated that a multistatic (MS) formulation of the ambiguity function can be used to analyze MS radar systems. For these latter, the MS ambiguity function can be exploited as a guideline for developing MS radar signal processing rules and waveform selection strategies. In this paper, we develop the concept of MS ambiguity function such that it simultaneously characterize the effects on resolution performance of system geometry and transmitted waveforms of MS radar systems with multiple transmitters and receivers. Visual examples are provided to illustrate the possible resolution enhancement using MS technology and highlighting its additional dependence on the type of detection used to process the received signals.
