Based on the analysis of bistatic SAR geometry model, bistatic SAR echoed signal is modeled in the double range variables domain in this paper, and the relationship between the double range variable domain and the single range variable domain is established. Then a range-dependent Doppler algorithm for imaging processing airborne bistatic SAR raw data of the translationally invariant configuration is derived, and the effect of error of the algorithm is analyzed by simulating.

摘要该文通过对机载双基地SAR非移变几何模型的分析，建立了双距离变量域的回波信号模型，由于回波数据是在距离和域，该文推导了距离和变量与双距离变量的转换关系，解决了该模型向距离和变量域转换的问题；提出了适用于非移变模式的变多普勒参数的双基地RD算法，并对该算法中引入变多普勒斜率所存在的误差进行了仿真分析。

In this thesis, we study some aspects in analytic combinatorics. The main contents can be summarized as follows. In Chapter 2, by classical umbral method, we obtain some properties and identities of invariant sequences. More generally, we study the self-inverse sequences related to sequences of polynomials of binomial type and the self-inverse sequences related to Sheffer sets, and give some interesting results of these sequences.
