Abstract

Long time integration is a common work mode for multiple-input multiple-output (MIMO) radar. In this mode, the accumulation effect is seriously affected by range migration. To solve this problem, we derive an expression, which describes how the accumulation output changes with the target velocity, bandwidth, and other factors, based on the MIMO radar moving target echo model. This expression quantifies the relation between the range migration and the influence factors. It can be used to determine the range of the target velocity in which the motion compensation is needed. Further, through appropriate parameter selection, such as choosing a proper transmission bandwidth etc., the influence of the range migration on accumulation output is minimized. The correctness of the theoretical results is verified by simulations.
