Apparatus and method for moving target detection of mobile platform radar considering Altitude line clutter

摘要

A moving target detection apparatus and method for a moving platform radar considering altitude clutter are disclosed. The moving target detection apparatus includes a main clutter coming through a main lobe, an altitude line clutter coming through a side lobe, and a radar signal including a moving target signal A first MTI filter unit for removing the altitude clutter from the received radar signal using a first MTI (Moving Target Indication) filter, a first MTI filter unit for removing the altitude clutter so that the Doppler frequency of the main clutter is 0 Hz, A second MTI filter unit for removing the main clutter from the compensated radar signal using the second MTI filter, and a cluttering unit using the staggered pulse repetition frequency. A blind speed compensator to increase the blind speed of the removed radar signal and a moving target detection sensor from the blind speed increased radar signal And an output unit for outputting and outputting.
