Surface moving targets selection with aperture synthesing mode taking account with antenna phase center (APC) forward - circular movement is considered in this work. It`s assumed that APC moves forward by radiolocation system carrier moving, and also moves sircularly about the carrier mass center taking account real antenna boarding on rotor blade tip. Issues of observation moving targets echo signal processing are considered. It`s supposed, that seeing object is point target, moving forward with constant velocity. Trajectory signal processing is carried out by direct convolution method. Processing system output response dependence of observation time, APC and point target moving parameters is considered. Comparative analysis of output responses during configuration of optimal processing system for moved and stationary target was carried out. Moving target selection is carried out by inter-period subtraction system. Magnitude-frequency and faze-frequency responses were analized during this work. Research of output response signal magnitude dependence on target moving velocity on known direction was also carried out. That is, the purpose of the research is selection algorithm features and effectiveness analysis taking account combined APC movement during aperture synthesizing process. The studies shown that surface moving object selection is possible in different monitoring angle, the quantity of simulteniously selected moving targets is only depended by computing system performance; process of selection and radioimage creation isn`t depend on target moving direction.
