碩士 / 國防大學中正理工學院 / 電子工程研究所 / 89 / In this thesis, we describe the characteristic of sea clutter distribution by range-doppler space in an airborne pulse-doppler radar system. The shape parameter of the weibull PDF is linely related to the grazing angle. Generally, the mean reflectivity of sea clutter dependent on sea state,radar frequency and grazing angle and it can be modeled by a polynomial.
The closed-form equation derived by Jao and Goggins is adopted here. This equation can be applied to caculate the power density spetrum of sea clutter to avoid the integration operation.
In application, we present simulation results with clutter maps based on various duty-cycles and sea-states, and analyze the doppler spectrum in each range bins.
