Abstract:

Accurate range alignment is the foundation of inverse synthetic aperture radar (ISAR) imaging. A method for the range alignment suitable to engineering application is presented. By survey correlation of each grouping pulse, the length of the window function is adjusted, so the drift error and burr are eliminated. The starting place is selected by competition, thus the steadiness of the algorithm is ensured. Firally, the processing of simulated and real data shows that the proposed method can meet the requirements of the imaging.
