  1. Targets in the radar ppi have the main property of the little area, a few targets and irregular change of grey. so it is difficulty to detect and track the target. the study of the radar ppi is very few inland and abroad. with the development and implement of high resolution radar and high resolution raster display, target _ tracking and detecitng based on the radar ppi will be feasible. it ' s great excellence is to increase time accumulation compare with the detecting techenicial of the traditional radar

    ppi中的特是面積小,或可能的多,灰度、形狀變化無明顯規律,所以檢測和跟蹤比較困難。基於ppi的研究國內外甚少,隨著高解析度和高分辨柵顯示器的發展,基於ppi的檢測和跟蹤成為可能。與傳統的檢測技術相比,其潛在的優勢在於大大增加了信號的時間積累,因此有可能提高檢測性能。
  2. ( 2 ). according to the system indices and requirements together with the technology characteristic, it researches the capture possibility of apt capturing system. then it introduces the common scan methods, such as raster, spiral, raster spiral, rose and lissajo. ( 3 ). it makes a detailed simulation analysis of the raster and spiral scan, analyze the connection between capture probability, capture time, system index at different capture resolution angle, capture range, vibration angle extent and terminal location distributing mean square deviation

    其中對幾個關鍵部分進行了詳細分析:計算了角反射器的激散射截面( lrcs )值,研究了qd與ccd對位置角度的計算方法和空間解析度; ( 2 )根據系統指和要求並結合現有國內技術特研究了apt捕獲系統掃描的捕獲概率問題,然後分析了幾種常見的掃描方式:矩形( raster )掃描、螺旋( spiral )掃描,矩形螺旋( rasterspiral )掃描,玫瑰形( rose )掃描以及李薩如形( lissajo )掃描; ( 3 )對分行掃描和螺旋掃描進行了詳細的模擬分析,分析了它們在不同捕獲分辨角、捕獲范圍、振動角振幅和終端位置分佈均方差時的捕獲概率、捕獲時間與系統常數之間的關系。
  3. The algorithm features full utilization of different installation positions and different angular resolutions of the two lrfs by assigning different tasks to them. the top lrf was used to set up the initial trace of new obstacles recognized from the result of d - s evidence theory based multi - period data fusion and the bottom one was used to maintain tracking of obstacles, providing relatively accurate positions of the obstacles

    該演算法的特在於充分利用了兩個激測距的不同安裝位置、不同解析度對障礙檢測造成的有利條件,將多跟蹤的理論和技術融入障礙檢測的軟體框架中,並結合d - s證據理論融合多測量周期的識別結果,由頂建立障礙的初始航跡,而底進行航跡的跟蹤和維持。
  4. Based on fuzzy logic, an effective algorithm of edge connection is proposed. simulation result shows our approach can highly improve the connectivity of the extracted image boundaries without distortion. this work lays foundations of target detection, tracking, and recognition for photoelectric tracker and imaging radar

    通過理論分析及模擬結果證明,本文提出的梯度參數自學習統計的方法和基於模糊判決的邊緣連接方法能夠有效地提取邊緣進行邊緣連接,能夠在保持原有圖像不失真的情況下,較大地提高圖像邊界的連通性,為電跟蹤器和成像檢測、跟蹤和識別等提供良好的基礎。
