Abstract

The algorithm of ISAR imaging of space objects (R0 > 100 km, V~ 500–7000 km/s) using the radar with binary phase-coded signals is presented in the article. The algorithm is based on simultaneous determination of the speed and acceleration of several target points. The image brightness and tracks of the points are using to determine of their speeds and accelerations. The results of numerical modeling of three-point object are shown. The values of signal-to-noise ratio (SNR) when algorithm shows good results are found. For this value of SNR the algorithm doesn’t depend from noise.
