Multiple moment video detector

摘要: An improved video clutter processor utilizing a multiple moment detector that provides constant false alarm rate regardless of the probability distribution radar clutter. The an adaptive threshold is function moments to compensate for variation in parameter selected number distributors. In accordance with invention either around origin may be combined establish or central level. one arrangement invention, digital delay lines store quantized sample and second, third fourth powers which are mean values about estimated by dividing sum videos equal provide origin. obtained transform relations providing maximum likelihood method substantially near method. then multiplying each factors K i adding these plus factor o corresponds offset term. Thus, T all four it able variations parameters single, double, triple quadruple distribution. principles includes other arrangements deriving value combining any desired higher determined from moments.
