“…When the LFMCW technology is applied to the airborne radar, it not only enables the airborne radar to have many excellent performances of the LFMCW radar, such as good detection performance, high‐precision measurement performance, and anti‐jamming performance, and it helps to meet the requirements of the airborne radar for miniaturisation, lightweight, and low power consumption [5]. At present, there are already examples of applications of LFMCW technology in synthetic aperture radar (SAR) imaging and moving target detection [6, 7], at the same time, some scholars have conducted relevant theoretical research on LFMCW SAR under the downward‐looking and forward‐looking working modes [8]. On the other hand, in the detection of moving targets, the single‐channel radar has better detection effect on the fast ones, but it cannot detect slow ones in the main lobe clutter.…”

Combined with Frequency-Modulated Continuous-Wave (FMCW) technology, airborne forward-looking array synthetic aperture radar (SAR) can obtain the image in front of the aircraft and also have the advantages of FMCW radar such as small size and lightweight. Moreover, it is suitable to be installed on platforms like helicopter and small unmanned aerial vehicle. It's valuable to study the imaging problem of airborne forward looking array SAR when aircraft platforms move toward the target areas in practice. This paper analyses the echo model based on geometry of forward looking array SAR and the Doppler frequency shift due to the movement of the aircraft platforms with a forward and downward velocity, studies a corresponding correction scheme and then presents an improved frequency scaling algorithm for forward looking array FMCW SAR. Finally, the algorithm is verified with the simulation and discussion.
