Examples
- Chapter 1 concisely introduces the principle of sar , the resolution of range direction and azimuth direction , result of the impulse compression , the principle model and application of sar
第一章介绍合成孔径雷达的距离向、方位向分辨率概念，脉冲压缩的作用，以及合成孔径雷达的理论模型、优缺点和应用。 - Firstly , the principle of high resolution sar and theoretical imaging model were concisely introduced . pulse compression for line frequency modulation pulse signal , resolution of range direction and azimuth direction , and doppler history were discussed subsequently . in accordance with sar signal processing , range immigration was also involved
本文首先分析了合成孔径雷达高分辩力成像机理和sar成像理论模型，讨论了线性调频脉冲信号的匹配滤波(脉冲压缩) 、 sar距离特性、方位特性和多普勒历史，同时针对sar成像信号处理，分析了成像处理的基本原理和成像处理中的距离迁移校正等关键问题。 - Synthetic aperture radar ( sar ) has been widely used in both military affairs and civilian fields because of its high - resolution , independence of both time and weather conditions , etc . usually , sar could only be used to detect and image static targets instead of moving targets for the reason that the position drifting will make local mistake in the general sar image , which is usually caused by the velocity of the moving targets in the ground range direction , and when it comes to the target with strong scatter coefficient right in the drifting position , the moving target could not be detected at all
合成孔径雷达( sar )由于其高分辨率、全天时、全天候等优良性能,已经在军事和民用领域得到越来越广泛的应用。通常,合成孔径雷达只能对静止目标进行检测和成像,动目标由于其径向速度而在常规sar图像中有一个位置偏移,使成像造成局部错误,而且当偏移处有强散射目标时,动目标将无法检测。军事上的应用也要求合成孔径雷达能对运动目标进行有效地检测和成像,因而运动目标检测( mti )及其成像日益成为合成孔径雷达领域研究的一个热点。
