A large number of relaxation schemes for feature mapping, claimed to be invariant to transformation, have been reported. However, most of them can deal with transfor-mations involving only rotation and translation, but not scaling. To stay away from the issue of scaling, unrealistic assumptions have to be imposed, such as the conjectures that range data are available so that objects can be rescaled before mapping, and that object shapes are complete so that ratios between object shapes and prototypes can be figured out beforehand. In this paper, we propose a relaxation scheme which is able to be in-variant at a time to rotation, translation, as well as scaling.

截至目前为止已有不少供几何特徵匹配用之松弛法架构被提出来，这些架构虽然宣称可以对空间转移具有不变性，但是实际上，大部分只能处理和旋转及平移有关的转移，对於具有尺度因素的转换泽尽量避免，因此，便有各种不同的假设被加诸於所考虑的问题，例如假设我们已知景深值，因此可以先将物件的尺度正规化后再比对，或者假设物形式晚整的，於是物形和模型间的尺度比率事先可以推知。

a system of along-track mode sar based on the gps is established.by seeing the gps signal as a chirp,chirp scaling algorithm of this mode with large squint angle is investigated.chirp scaling algorithm is considered more efficient and widely applicable when the bistatic sar system is in side-look or small squint angle mode,but in large squint angle case,the errors caused by taylor expansion are so large that the algorithm could lose its precision.in such a case,an equivalent mono-static sar range mode which has fewer errors than taylor expansion with large squint angle is proposed to substitute the range history of bistatic sar.then bistatic sar images with large squint angles are gotten by common nonlinear cs algorithm.the effectivity of the method is verified by matlab simulation.

摘 要：建立了基于gps的顺轨sar系统模型，通过将gps信号等效为chirp信号，研究了在该模式下的大斜视角chirp scaling算法。在正侧视或小斜视情况下，cs算法具有较好的聚焦性能和广泛的适用性，但在斜视角较大的情况下，该算法将散焦而不能成像，因而提出了用等效的单基地距离模型来代替双基地距离历史的方法，解决了大斜视角情况下距离模型二阶近似误差较大的问题，并结合单基地非线性cs算法，实现了在大斜视角情况下的基于gps反射信号的双基地sar高精度成像，最后通过matlab仿真进行了验证。
