Abstract

A high subclutter visibility (SCV) noncoherent VHF radar is introduced. By increasing the frequency stability of the system through the de-Q amplitude stabilized circuit, four-port circulator, decimal frequency divided phase locked loop and so on, and improving the capability of the signal processor through digital convolution, three-pulse cancellation, CFAR, AND sliding window integration, the SCV is more than 30 dB
