Abstract :
This paper investigates the problem of detecting the strong scatterers by use of inverse synthetic aperture radar (ISAR). Three methods are proposed. They are maximal average amplitude, minimal entropy and maximal energy. The proposed methods are compared with the existed approach i.e. minimal variance. We carry out the experiment by processing the live data of Boeing-727 aircraft provided by Prof. B.D. Steinberg. The detection results are given graphically. Based on the detected strongest scatterer of target, we perform the phase compensation of ISAR by the scatterer reference method. The reconstructed image of Boeing-727 is also shown
