A Processing Detection Project Research of Weak Targets in the Complex Ground Clutter

The paper present a project of improving the weak targets detection capability in the complex ground clutter at the same time maintaining the hardware´s simplicity for the air-ground millimeter-wave terminal guidance radar. The project use the wide band chirp-subpulse stepped-frequency signal to detect targets, and get the target region´s quasi two dimension image by processing the echo signal both in the time and frequency domain, thereby improving the weak target detection capability and providing the real guidance information. The theoretical analysis and computer simulation result proved the project´s validity.
