21266 俯冲合成孔径雷达(SAR)常采用大斜视子孔径成像来满足平台机动性和处理实时性； The diving SAR usually adopts the highly squinted mode and sub-aperture to satisfy themaneuvering and real-time processing.
21267 而大斜视模式下距离方位的严重耦合、斜视角沿距离向的空变及3维速度和加速度的存在会导致距离包络和方位相位的2维空变，严重影响成像质量。 However, the existence of severe range-azimuth coupling, range-dependent squint angle and three-dimension velocity and acceleration leads to the space variance of rangeenvelope and azimuth phase, which makes imagery unfocused seriously.
21268 针对这些问题，该文提出一种新的两级频域滤波算法， To solve these problems, a Two-stageFrequency Filtering Algorithm (TsFFA) is proposed.
21269 在预处理后，首先引入第1级频域滤波因子以校正距离包络沿方位位置的空变以实现距离徙动统一校正， After preprocessing, the First-stage Frequency Filtering(FsFF) factor is first introduced to correct azimuth-dependent Range Cell Migration (RCM) and realize theunified RCM correction.
21270 然后采用第2级频域滤波校正方位多普勒参数的空变实现方位相位统一聚焦。 Furthermore, the Second-stage Frequency Filtering (SsFF) factor is adopted toequalize azimuth-dependent Doppler parameters and realize unified azimuth phase focused.
21271 仿真实验验证了该算法的有效性。 Simulation results are presented to validate the effectiveness of the proposed approach.
21272 针对高动态环境下双二进制偏移载波(DBOC)调制信号无法精确捕获的问题，该文提出一种基于部分匹配滤波结合快速傅里叶变换(PMF-FFT)的捕获方法。 For the problem of without accurate acquisition of Double Binary Offset Carrier (DBOC) modulatedsignal for high dynamic environment, a method which is based on Partial Matched Filtering (PMF) - FastFourier Transform (FFT) is proposed.
21273 又针对捕获过程中相关损失和扇贝损失引起的检测性能降低问题，提出一种改进的捕获方法。 According to the problem of low detection performance caused by therelated loss and scallop loss, a new improved acquisition scheme is proposed.
21274 该方法首先利用离散多项式相位变换(DPT)去除接收信号的高阶动态项，然后针对DBOC信号重新设计PMF-FFT算法； Firstly, the Discrete Polynomialphase Transform (DPT) is used to remove the high order dynamic term of the received signal, and then thePMF-FFT algorithm is redesigned for the DBOC signal.
