Method for inverse synthetic aperture radar imaging of space debris using improved genetic algorithm
, 2017Due to the rapid spinning of space debris, its radar echoes have serious migration through range cells and highly non-stationary, time-varying Doppler. With low pulse repetition frequency (PRF) and data missing, conventional joint time–frequency imaging ...

In high-resolution inverse synthetic aperture radar (ISAR) imaging, the rotational motion of the targets tends to introduce the time-variant Doppler modulation in the echo, which acts as the range-variant phase errors in the phase history.

Three-dimensional shipborne inverse synthetic aperture radar imaging based on single receiver
, 2017Three-dimensional (3D) inverse synthetic aperture radar (ISAR) image can provide additional height information compared to conventional 2D ISAR image. However, since the existing 3D ISAR imaging methods concentrate on the interferometric technique, the ...
