Parameter selection algorithm of MIMO radar under long time integration

Long time integration is a common mode in MIMO(multiple-input multiple-output) radar.But the accumulation effect is seriously affected by range migration.To solve the problems mentioned above,this paper formulated the accumulation output changing with target velocity,bandwidth and other factors based on moving target echo model in MIMO radar.It quantificationally analyzed the relation between range migration and its influence factors.This formula can be used to determine target velocity on which motion compensation is essential,together with appropriate parameters such as transmission bandwidth selected to ensure range migration has the least influences on accumulation output.The validity of this theory is verified by simulation results.
