Abstract
Statement of a problem. Today a actual task is check of a radio-receiving path of the radar with synthesizing of an aperture of the antenna (SAR) in laboratory conditions.
Purpose. Justification of a possibility of check of a radio-receiving path of SAR in laboratory conditions.
Results. Digital imitation of the signals reflected from the surface being at a distance of 150 km from SAR when ensuring resolution on an azimuth of 2.5 m is offered. Dynamic range and sensitivity of SAR after two-dimensional convolution of radio holograms is measured (on an azimuth and inclined range).
Practical importance. Check of a radio-receiving path of SAR in laboratory conditions considerably saves time and cost of works. The exception of trajectory not stability inherent in real flight allows in ideal conditions to estimate radio engineering characteristics of SAR.
