Abstract:

Long-time coherent integration is a key technique for small moving targets detection under low signal noise.However,the integration and detection for long time should deal with the problem resulting from target range-cell-crossing.An effective way is to employ keystone transform to compensate the influence of range migration,thus achieving coherent integration of all moving targets regardless of their unknown velocity.The paper presents a complete set of algorithms for radar signal processing,and the effectiveness of the algorithms is confirmed.

Key words: long-time coherent ntegration;Keystone transform;compensate;SNR;range-cell-crossing
