static target meaning in English
静止目标
Examples
- Chapter 2 deals with the ground echo signal of sar , and establishes the signal models of static target and moving target
第二章研究了合成孔径雷达回波信号,建立了静止目标和运动目标的回波模型。 - The approch developed in this paper is applied to some real image data , and satisfied results are obtained . both the moving targets in a set of infrared images and the static targets in optical images can be detected automatically
将本文提出的研究方法用于实景图像分析，获得了满意的实验结果，既可自动检测出红外运动图像目标，也能提取多种光学静态图像目标。 - 3 . based on the unattended grounded sensor networks , the sensor configuration for a static target and moving targets are discussed , which show that sensors distributed uniformly on a circle is suitable for sensor networks initialization
以无人监视地面传感器ugs网络系统为背景，分析了针对静止目标的点优化布局和针对运动目标的面优化布局，得到了传感器均匀地分布在圆周上是较好的网络初始化布局的结论。 - 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。 - In this paper , the main problem is to detect the position and velocity of moving target by fractional fourier transform which could be concluded by three parts , the echo model establishment of moving target , the realization of fractional fourier transform and parameters estimation of moving target , detailed contents are as follows . firstly , the paper analyses the echo model of sar static target and introduces a kind of sar imaging algorithm , range - doppler ( r - d ) algorithm
