METHOD OF FORMING RADAR IMAGE IN RADAR STATION WITH SYNTHESIZED ANTENNA APERTURE Russian patent published in 2017 - IPC G01S13/89 

FIELD: radio engineering, communication.

SUBSTANCE: method of forming a radar image in a radar station with a synthesized antenna aperture consists in probing, receiving, storing echoes, determining the moment of the sounding onset, constructing a two-dimensional matrix by line-by-line reading the stored echo signal records, compressing two-dimensional matrix in range and azimuth. During the storage of the received echo at the moments of the sounding onset, inserting of pauses is performed with a duration τ_i by its amplitude manipulation, and during the detection of the sounding onset, the absolute value of the stored signal is integrated within the sliding window, which is a time strobe with a duration τ_i a varying time offset from the zero value corresponding to the beginning of the echo storage to a value equal to the sounding period, the time position of the obtained integral minimum is determined, which corresponds to the moment of the sounding onset.

EFFECT: increasing the resolution of the radar image at an inclined range and expanding the dynamic range by synchronizing the moment of the beginning of the echo recording with the next sounding onset.
