Popis: |
Bistatic inverse synthetic aperture radar (ISAR) makes use of non-back echo of target to form image, which solves the problem that the monostatic ISAR image could not be formed in some particular motion conditions. Due to the existence of bistatic angle, the azimuth resolution of bistatic ISAR is far smaller than the monostatic ISAR with the same bandwidth. To solve this problem, linear prediction algorithm is introduced to bistatic ISAR image. Based on the approximately linear character of azimuth echo, echo data is extended back and forth at the same time to expand bistatic echo. Equivalent pulse accumulation time is enhanced and the azimuth resolution is improved. Simulation experiment validates the efficiency of this algorithm. |
