摘要 随着对测绘带宽的要求,越来越多的使用阵列天线的SAR系统在距离向接收时使用数字波束形成(digital beam forming,DBF)技术,通过详细研究普通的DBF技术在对延伸距离较长、且测绘带内高度有明显变化的山坡地区,成像时由于天线增益损耗严重而导致叠掩效应加重的原理,并在普通DBF的基础上研究了一种基于脉内波束矢量(intra-pulse beam steering,IBS)技术的DBF方法,该方法在保持测绘带宽不变的情况下,对相同地区成像时可以有效降低天线增益损耗,并建立了其数学模型和进行了理论推导,最后通过计算机仿真比较了两种情况下天线增益损耗的差异和证明了脉内波束矢量(IBS)技术的有效性。 With the requirement of the wide swath, many SAR system use digital beam forming （DBF） on receive in elevation. The serious layover problem lead by the DBF was introduced, and DBF was used to receive the echoes from long mountainous terrain will cause antenna gain reduced due to erroneous beam pointing. Based on DBF, a new method, intra- pulse beam steering and its mathematics model were researched, which could keep the swath width and reduce the antenna gain loss. Finally, the antenna gain losses with the two methods were compared through simulating results. The validity of the intra-pulse beam steering （IBS） was proved at last.
