Range Migration Compensation Based on Keystone Transform in Sea Clutter

In Pulsed Doppler radar, when wideband signals are used and the target radial velocity is high, linear range migration occurs and cannot be neglected. The migration misaligns the range profiles within a coherent processing interval and degrades the coherent integration gain eventually. Keystone Transform is a method used for range migration compensation of fast moving targets. In this paper, diminishing effect of range migration by utilizing Keystone Transform in a realistic sea clutter environment is studied. For this, a realistic sea clutter environment is generated.
