  1. 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徑回波信號,建立了目標和運動目標的回波模型。
  2. Sea clutter mainly occurs close to the radar site. it appears as a stationary feature in an animation sequence

    海雜波主要出現在接近位置的地方,而在圖像動畫中一般是呈現不動的。
  3. Then an overview of the principle of sar is given, the computer model of the radar echo is discussed in detail, the simulation result of the ideal static point target and ideal static distributed target based on the computer model are presented

    在闡明合成孔徑基本原理的基礎上,深入地探討了合成孔徑的回波模型,並藉助此模型分別進行了理想點目標和分佈目標的回波模擬。
  4. 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

    本文的主要內容包括三個部分,即動目標回波模型建立、分數階傅立葉變換的實現和動目標參數估計,具體來說,其內容如下:首先,本文研究分析了合成孔徑雷達靜止點目標的回波模型並介紹了一種基本的合成孔徑成像演算法? ?距離-多普勒( r - d )演算法。
  5. 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

    合成孔徑( sar )由於其高解析度、全天時、全天候等優良性能,已經在軍事和民用領域得到越來越廣泛的應用。通常,合成孔徑只能對目標進行檢測和成像,動目標由於其徑向速度而在常規sar圖像中有一個位置偏移,使成像造成局部錯誤,而且當偏移處有強散射目標時,動目標將無法檢測。軍事上的應用也要求合成孔徑能對運動目標進行有效地檢測和成像,因而運動目標檢測( mti )及其成像日益成為合成孔徑領域研究的一個熱點。
