DEVICE TO IDENTIFY AIR RADAR OBSERVATION OBJECT WITH SELECTION OF INTERVAL FOR MAXIMISATION INTERVAL OF ITS TURN AT TRAJECTORY INSTABILITY OF MOTION

摘要

FIELD: physics. ^ SUBSTANCE: known device additionally provided with ADC, unit of smoothing peaks determination, data storage unit and identification tag computation unit, all being interconnected with connected with other elements of proposed device. Proposed arrangement of device allows generating identification tag to express variation in levels of reflected signals at varying object range finding aspect angle solely at intervals with maximum angular speed of object frame turn relative to radar. Such interval is determined by memorising reflected signals during surplus analysis interval of about 5 seconds to allow correlation analysis of shaped and memorised amplitude reflectivity of an object. Turn angular speed maximum is found by minimisation of autocorrelation factor of reflection frequency sample. ^ EFFECT: higher probability of identification. ^ 3 dwg
