Abstract

In recent years Multiple-Input Multiple-Output (MIMO) radar has been shown to offer enhanced performance. In traditional radar systems Woodward’s ambiguity function (AF) is normally used to characterize the performance of the operating waveform. Due to their higher degrees of freedom (DOF) however, MIMO radars’ performance cannot be sufficiently characterised by Woodward’s AF. While many formulations of MIMO AF have been proposed addressing different necessities for system characterisation, most of them do not provide a complete tool covering all the DOFs. In this paper we examine how parameters such as array geometry, operating waveform, and target model can effect the performance of the overall system. Additionally we propose a MIMO AF definition based on Kullback-Leibler divergence and compare it with different proposed formulations.
