多通道SAR系统地面运动目标信息获取方法研究

摘要
雷达成像技术作为一种全天时、全天候、远距离的信息获取手段在国防以及民用领域都具有重大应用价值，它大大提高了雷达信息获取能力，为目标识别创造了前所未有的机会，是雷达技术发展的一个重要里程碑。地面运动目标检测是军用合成孔径雷达系统所必须具备的一项基本功能，也是其信号处理中的一个重要问题。由于沿航迹向多通道SAR比单通道SAR能够提供更多的系统自由度，具有很好的杂波抑制性能，能在地杂波或者海杂波中清楚地区分出运动目标并且能够正确地估计出其运动参数，因而广泛地应用于战场感知和侦查中。本论文以正侧视多通道SAR-GMTI系统为对象，具体研究内容如下：
第一部分，为了获得水平和垂直的多个相位中心信息，提出了一种新的卫星基线斜置并结合相位中心偏置天线技术的星载三通道SAR-GMTI方法。研究了基线斜置时的等效相位中心补偿函数，给出了在该情况下新的系统约束条件，并在此基础上分析了基线斜置角对检测盲速的影响。
第二部分，针对多通道SAR-GMTI系统中通道间存在幅度、相位误差的问题，分析了幅、相误差对静止目标抑制和运动目标检测的影响。提出了一种以伪随机码作为校准源进行通道幅、相误差计算的方法，该方法利用校准源发射伪随机码信号，然后在各接收通道中利用相关解扩计算出幅度和相位误差，并结合卡尔曼滤波器来消除噪声对误差计算的影响。与传统的傅立叶变换相比，所提方法在低信噪比的情况下具有更好的误差测量效果。
第三部分，单通道系统对落入主瓣杂波内的慢速运动目标难以检测，而多通道SAR-GMTI具有良好的杂波对消性，不仅能够检测慢速运动目标，而且还能对目标进行参数估计和定位处理。因此，本文着重对多通道SAR-GMTI的误差问题进行了分析。同时，在多输入多输出合成孔径雷达的基础上，提出使用双卫星、双工作频率实现地面快速运动目标检测、成像和参数估计的方法。利用广义二阶keystone变换对提取出的运动目标进行距离徙动校正，针对快速运动目标的多普勒模糊问题，使用修正的离散调频傅立叶变换结合最小波形熵搜索完成目标多普勒参数估计，利用数值搜索的方法对不同工作频率下的速度集合进行交集求解得到目标真实速度值。
第四部分，不同于匀速运动目标，当目标具有加速度时会使回波产生方位向上的三次相位，影响静止目标抑制和多普勒参数估计，为此，提出了一种基于三次相位补偿的参数估计方法。在分析信号模型的基础上，通过在时间-调频率平面上采用类似Dechirp和一维搜索的方法实现三次相位的补偿，并提出了一种基于三次相位补偿的方位向速度估计方法。
第五部分，研究了同步轨道卫星结合机载双通道SAR的双基地SAR-GMTI系统。在分析运动目标回波信号的线性调频特性后，根据该特性利用分数阶傅立叶变换进行多普勒参数估计，以此构造新的补偿函数和匹配滤波器，并对双基地系统中的时间、频率不同步影响运动目标聚焦成像的问题进行了详细分析。从星机双基地SAR-GMTI的运动误差几何模型出发，分析出误差对运动目标参数的影响，并给出了相应的补偿因子。特别针对地势起伏和斜视角不能忽略的情况，分析了误差补偿的偏移量并提出了有效的补偿方法。
Due to its all-weather, all day/night and long range, radar imaging technique canenhance radar’s information acquisition capability greatly, thus exhibits great value inboth civilian and military applications. It provides strange change for targetidentification. At the same time, it is also a landmark for development of radartechniques. Ground Moving Target Indication (GMTI) is a necessary function of theSAR system, especially in military SAR application and signal processing. Since two ormore antennas (channels) can provide more degrees of freedom, multi-channelalong-track SAR has powerful ability to suppress clutter and distinguish targets movingon land or water from surface clutters over a large area. Thus it has been usedextensively in air-to-ground surveillance and reconnaissance. The primary contributionsof this dissertation, which is devoted to the above aspects, are summarized as below:
1. In order to obtain a number of horizontal and vertical phase center information,a novel spaceborne SAR-GMTI with three-channel is proposed, which is based onslant-placed baseline and displaced phase center antenna. The compensation functionfor equivalent phase center with slant-placed baseline is analyzed. New constraint of thesystem and analysis of blind velocity relative to slant-placed antenna are also given.
2. Aiming at channel errors in multi-channel SAR-GMTI, the influence of errorson clutter suppression and moving target detection is analyzed. A novel method ofamplitude and phase errors calculation is presented based on the PN code. It transmits aPN code from calibration source, and use decorrelation to get amplitude and phaseerrors in each receiving channel. Finally, Kalman filter is applied to eliminate the effectof noise. Compared with the traditional Fourier transform, the proposed method hasbetter effects in the case of low SNR.
3. Multi-channel SAR-GMTI has a good character of clutter cancellation, it is notonly able to detect slow moving targets, but also on the target parameter estimation andpositioning processing. Therefore, the errors of multi-channel SAR-GMTI wereanalyzed in detail. Based on the multiple-input multiple-output synthetic aperture radar,an approach with dual-satellites dual frequency for detection, imaging and parametersestimation of the ground fast moving target is proposed. General two-order keystonetransform is employed to eliminate range migration, modified discrete chirp-Fouriertransform and least waveform entropy are applied to Doppler parameters estimation. Forthe Doppler ambiguity of fast moving target, velocity can be obtained by search ofdifferent frequency data.
4. Different from the target of uniform motion, moving target makes cubic phasewhen it has acceleration. It affects clutter suppression and Doppler parameter estimation,so a parameter estimation method based on cubic phase compensation is proposed.Based on the analysis of signal model, phase compensation is achieved by dechirp andone-dimensional search in time-chirp distribution. And velocity estimation is proposedbased on the cubic phase compensation.
5. A bistatic SAR-GMTI system which is the combination of geosynchronoussatellite and airborne dual-channel SAR is researched. According to the analysis ofmoving target signal characteristics, new compensation function and matched filter areconstructed by FrFT. The problem of imaging affected by time and frequencyasynchronization is analyzed in detail. Based on the signal geometry, motion errorinfluence on parameters of moving target is deduced, and the correspondingcompensation factors are also proposed. Especially for the case when relief and squintcannot be ignored, offset error compensation and an effective compensation methodwere obtained.
