Abstract EN
SAR raw signal simulation under the case of maneuver and high-speed has been a challenging and urgent work recently.
In this paper, a new method based on one-dimensional fast Fourier transform (1DFFT) algorithm is presented for raw signal simulation of maneuvering target for missile-borne SAR.
Firstly, SAR time-domain raw signal model is given and an effective Range Frequency Azimuth Time (RFAT) algorithm based on 1DFFT is derived.
In this algorithm, the “Stop and Go” (SaG) model is adopted and the wide radar scattering characteristic of target is taken into account.
Furthermore, the “Inner Pulse Motion” (IPM) model is employed to deal with high-speed case.
This new RFAT method can handle the maneuvering cases, high-speed cases, and bistatic radar cases, which are all possible in the missile-borne SAR.
Besides, this raw signal simulation adopts the electromagnetic scattering calculation so that we do not need a scattering rate distribution map as the simulation input.
Thus, the multiple electromagnetic reflections can be considered.
Simulation examples prove the effectiveness of our method.
