TRIANGULAR METHOD OF CONSTRUCTION OF 2D RADAR IMAGE OF TARGET IN TRACKING RADAR WITH INVERSE SYNTHESIZED APERTURE Russian patent published in 1997 - IPC

FIELD: radiolocation. SUBSTANCE: it is suggested to analyze structure of Doppler portraits of target obtained with change of location aspect through 0.5 deg to increase accuracy of construction of radar image. Coordinates of local scatterers of target surface are computed on basis of analysis in system of coordinates coupled to center of tracking of target. Method is invariant to position and change of Doppler frequency of center of tracking of target and is devoid of collection of errors in construction of image coupled to various assumptions adopted in prototype. EFFECT: increased quality of identification of air targets. 1 dwg
