This paper proposes a new flexible method of the beam shaping based on superposition principle and the scanning principle of phased array antenna. We designed a 145cm × 48cm array composed of microstrip patch elements with the wavelength of 24cm. In the azimuth direction, the pattern of this array has 23?half-power beam width. According to the principle of the synthetic aperture, the azimuth spatial resolution of the strip SAR is improved dramatically with wide beam. In this paper, the wide beam antenna array is used as the antenna of an airborne SAR with ultrahigh azimuth resolution. The parameters of the antenna and the SAR system are calculated and are compared between the strip-mapping SAR and the Spotlight SAR.

运用多相位中心多方位波束(MPCMAB)技术能够有效解决条带模式的常规星载SAR系统中方位向分辨率与脉冲重复频率之间的矛盾.通过分析多相位中心多方位波束SAR与常规条带SAR回波数据之间的内在联系,提出了多相位中心多方位波束SAR的回波数据分通道相位补偿和多通道有序组合的成像算法.仿真证明了该技术的有效性.

The signal of missile-borne strip SAR has a feature of small range curvature,when the request of resolution is not very high ,the range curvature can be ignored if the maximum range curvature is smaller than a range resolution cell. This paper presents an imaging method of correcting range migration in frequency domain, and a method of combining the rang error correction and geometry correction,which can make the imaging efficiency better.Finally,simulation results verify the method.

弹载条带式SAR信号特点表现为小的距离弯曲量,当分辨率要求不是特别高时,若最大距离弯曲量小于一个距离分辨单元时可忽略不计,而只考虑距离走动量的校正。针对这一特点提出了一种在频域对距离迁移的线性项即距离走动校正的成像方法,并提出了距离误差校正和图像几何校正相结合的方法,使得成像效率更高。仿真成像结果验证了该方法的可行性。
