Description

technical field [0001] The disclosure belongs to the technical field of radar, and in particular relates to a moving target detection system associated with stationary target imaging and a detection method thereof. Background technique [0002] The ground moving target detection is to install the airborne radar on the air platform to detect the ground moving target, which is an important function of the airborne radar. [0003] In modern airborne multifunctional radars, in addition to the static target imaging mode, the ground moving target detection function is also generally integrated. One of the ground moving target detection working methods is that the stationary target imaging and the ground moving target detection work simultaneously, that is, in the Ground moving target detection is performed while the stationary target is imaged, and the detected moving target can be marked on the synchronously generated radar image in real time. In this way, the stationary target i...

AI Technical Summary

Problems solved by technology

[0004] The moving target detection of airborne radar is closely related to the movement of the airborne platform. Usually, the movement of the airborne platform will cause the ground carrier spectrum to broaden and the frequency center to shift, which will affect the detection ability of the moving target and the estimation of the motion parameters of the detected target. have a big impact

Generally, the navigation equipment of the carrier platform can be used to estimate the motion parameters of the carrier platform, and then use these motion parameters to compensate the moving target detection, but this method will cause the detection performance of the moving target to depend on the accuracy of the carrier platform navigation equipment
