Sea clutter is the reflected signal in the reverse direction from the sea surface. Radar Signal Processing has the ability to model the Doppler spectral characteristics of clutter to achieve effective detection and tracking of targets on the sea surface. This paper aims to develop a high frequency resolution technique for modeling the Doppler spectral characteristics of clutter, estimating the clutter intensity, Clutter to Noise Ratio (CNR), clutter shape parameter, at each Doppler bin and noise component for real time clutter data of Range gate 1. It is shown that clutter is confined more to the center part of Doppler spectrum. And CNR is estimated in all range gates 1to 96, and also an approximate second order nonlinear mathematical model is developed for the variation of CNR as a function of range.
