PURPOSE:To make optimum clutter suppression possible by discriminating statistical distribution characteristics of a clutter amplitude to suppress clutter. CONSTITUTION:A Weibull distribution function setting circuit 3 determines a distribution function F(U) in accordance with a logarithmic conversion value U of a radar reception signal due to a logarithmic amplifying circuit 1 and an A/D converting circuit 2 and impresses it to a Weibull converting circuit 4. A converting circuit 42 operates and determines a value Y based on an equation I in accordance with a shape parameter K and a scale parameter delta set by a convertion parameter setting circuit 41 of the circuit 4. On a basis of this value Y, an amplitude characteristic discriminating circuit 5 calculates an inclination parameter, which is given by a formula II, in accordance with a value W defined by the integral value from the value Y to the infinite of the Weibull function and a value Z defined by lnY; and if a prescribed number of inclination parameters are equal to the parameter K, statistical distribution characteristics of the clutter amplitude is discriminated as a Weibull function distribution. Similarly, a log normal distribution is discriminated, and an optimum clutter suppression is performed in accordance with distribution characteristics.
