Radio imaging of low-orbit satellites from narrow-band radar data

A technique is presented for the radio imaging of low-orbit space vehicles with the help of narrow-band radio signals. The technique is based on the m ethod of inverse synthesis of radio holograms using variation in the object aspect angle during its motion along the orbit. Resolution of the method w as estimated and experimental conditions were obtained based on the numeric al simulation of the radar experiment. The radio image of the Progress spac e vehicle obtained from the radar data is presented.
