Models of the Sea Mixed Waves in Navigating Radar Simulator

Abstract

The sea mixed wave models of Radar simulators in existence only use the random number produced by computer to simulate simply ..donýt use the statistic discipline and mathematical model, the effect of simulation is not good, the fidelity of radar echo image is affected. The echo intensity of the sea mixed wave accords with Weibull distribution is discovered through researching on the statistic rule of the sea mixes wave. The inverse function of Weibullýs probability distribution function has been used to random numbers with Weibull distribution. The shape parameter and intensity parameter of Weibull distribution is given combined with the experimental accumulation and the distributing circumstance of real radarýs sea mixed wave under different range and sea situation.
