23395 对 FFT 计算过程进行优化，降低新算法的计算量，使其满足 3 维成像声呐实时性的要求。 The FFT computation process is optimized to reduce the computational complexity of the new algorithm to meet the real-time requirements of 3D imaging sonar.
23396 仿真与实验结果表明，采用分区域 FFT 波束形成算法的成像分辨率较传统均匀FFT 波束形成算法有显著提高，且满足实时性要求。 Simulation and experimental results show that the imaging resolution of the sub-region FFT beamforming algorithm is significantly higher than that of the traditional uniform FFT beamforming algorithm, and satisfies the real-time requirement.
23397 角闪烁是末制导阶段角跟踪误差的主要来源，如果对角闪烁处理不当会增大雷达跟踪目标的误差, 甚至丢失目标。 Angular glints are the main error sources for radar angular measurement in the terminal guidance, which may result larger tracking error or even lead to losses of the tracking if mishandled.
23398 通过脉冲压缩获得高分辨距离像是抑制角闪烁的一种有效方法，但仍不能完全消除测角误差。 Although the angle glint can be suppressed to some extent through Higher Range Resolution Profile (HRRP) processing, the tracking errors due to multiple scattering centers can not be thoroughly eliminated.
23399 研究发现高分辨成像对角闪烁的抑制效果与散射中心类型以及其方位特性相关。 It is found in this paper that the tracking errors are closely related with the attributes of scattering centers.
23400 该文从理论上分析了局部型、分布型、滑动型等不同的散射中心类型对角跟踪产生的影响，然后通过全波法电磁计算结果验证理论分析结论。 The influence on angular measurements induced by scattering centers with various attributes is investigated theoretically and numerically in this paper. For high reliability of numerical results, the scattering responses of extended targets are simulated by the scattered fields computed by the full-wave numerical method in this paper.
23401 该文研究结论对于抑制角闪烁、改善和提高雷达跟踪目标的性能具有参考价值。 The reached conclusion of this paper can provide a theoretical reference for the techniques in order to improve the tracing accuracy of extended targets with multiple scattering centers.
23402 在高帧率的视频合成孔径雷达(VideoSAR)成像模式获得的图像序列中，多普勒频移使运动目标在实际位置留下阴影，且相邻帧图像具有很强相关性。 In the image sequence obtained by the high frame rate Video Synthetic Aperture Radar (VideoSAR) mode, the Doppler shift results in some shadows of the moving targets in their actual position, and a strong correlation exists between adjacent frames.
23403 该文针对上述现象提出一种VideoSAR图像中动目标阴影检测的方法。 Based on the above rationale, this paper proposes an approach to detecting moving targets' shadow in VideoSAR imagery.
23404 首先，对每帧图像通过结合尺度不变特征变换(SIFT)和随机抽样一致性(RANSAC)算法实现配准并进行背景补偿，再采用CattePM模型抑制相干斑噪声。 First, the Scale-Invariant Feature Transform (SIFT) with RANdom SAmple Consensus (RANSAC) registration algorithm is used to compensate for the change of background of each frame, and the CattePM model is employed to suppress the speckle noise effectively.
