  • 摘要: 隨著合成孔徑雷達(SAR)的發(fā)展，對目標細節(jié)的觀測越來越受到重視。SAR圖像的分辨率越高，獲取的細節(jié)信息就越多。目前，一種實用性較高的技術(shù)是，利用步進頻率線性調(diào)頻信號波形獲取超高分辨率SAR圖像。這種技術(shù)基于不同子帶信號的步進載頻關(guān)系，通過子帶拼接來合成大帶寬信號。然而，子帶拼接對于基帶信號誤差非常敏感，該文首先提出一種基于回歸和統(tǒng)計學的信號預失真方案。在補償完子帶內(nèi)的誤差后，將子帶間的誤差轉(zhuǎn)化為一個多變量的優(yōu)化問題。最后，通過X波段機載SAR系統(tǒng)飛行實測數(shù)據(jù)驗證了所提方法的有效性。
    Abstract: The past decades have witnessed an increasing attention for detailed observation with developing of Synthetic Aperture Radar (SAR). The higher the resolutions of SAR images are, the more detailed information can be obtained from the images. At the present stage, the stepped frequency chirp signal waveform is a technology with high practicality to achieve the high range resolution imaging. The system can use the stepped frequency relationships between sub-band signals and then the sub-band synthesizing technique is applied to synthesize a large bandwidth signal. However, the sub-band synthesizing technique is very sensitive to the baseband signal error. A signal pre-distortion scheme is firstly proposed based on regression and statistics in this manuscript. After compensating the error in sub-band, the problems of errors between sub-bands are transformed into a multi-variable optimization problem. Finally, the effectiveness of the proposed method is verified by the X band airborne SAR system.
