Research distribution rules on marine moving target is of significance in operation decision-making in anti-ship missile. On basis of analyzing the connotation of target position distribution caused by certain speed(CS) and uncertain course(UC) under initial circular normal distribution(CND), CND-CS-UC distribution probability density model is built by means of conditional probability density method. Four properties on CND-CS-UC distribution are demonstrated, and optimized computing method for target probability in square and circular distribution area is induced. As a result of theoretical derivation and numerical analysis, CND-CS-UC distribution probability density in cartesian coordinate is symmetrical on vertical spatial plane through the distribution origin, and equivalent probability density curves of CND-CS-UC distribution are concentric circles. In polar coordinate, CND-CS-UC distribution probability density is closely to normal distribution when target motion distance was greater than three times mean square deviation of locating target, and coincidence degree between CND-CS-UC and normal distribution is above 94.97%.
