| Abstract: | The uniform angular speed and uniform angular acceleration rotational target multi-static ISAR two-dimension turntable models and imaging algorithms were proposed respectively.Furthermore,multi-static ISAR two-dimension turntable imaging constraints were analyzed.Based on the azimuth Doppler equations and range direction projection equations deduced by multi-static ISAR two-dimension turntable model,the positions and movement parameters of target scatters were obtained.The multi-static ISAR two-dimension tu... |
