A method for multiple ship target imaging based on hybrid SAR/ISAR method

In Airborne radar imaging of ship targets on the river (or the sea), itpsilas difficult to image each targets because each individual target may have its own motion characteristic different from others. Aim at this problem, this paper proposed a Airborne hybrid SAR/ISAR method imaging of muti-ship targets. By this method, the raw data is processed by SAR algorithm firstly, then, extract and recover of selected ship data from SAR image. Finally, ISAR image of selected targets. the effectiveness of the proposed method is verified by the real data processing.
