Based on the model of safe following distance, the design blue print of system is presented in the text. using the multiple impulses horae rotate speed sensor to measure the vehicle speed and nanometer radar to measure the distance of own vehicle to frontal vehicle, and analyzing and judging collected information by at89c51 which is the control centre of the system
本文在安全跟車模型的基礎上,提出了系統方案:採用霍爾多脈沖轉速傳感器測量汽車的速度,毫米波雷達測量兩車的距離和相對速度,利用at89c51作為信息採集單元的控制中心,對各種信息進行分析判斷,當行車距離小於報警距離時啟動相關的報警單元。The current radar scout system has some problems for processing multiform signals, confronting the complex electromagnetic environment and various radar characteristic signals. the adaptive front - end in receiver can solve these problems, and this dissertation analyzes it
面對日趨復雜的電磁環境以及變化繁多的雷達特徵信號,現有的雷達偵察接收系統對多種信息的處理顯得力不從心,本文從接收機前端考慮,對其中的一種解決方法? ?自適應的接收機前端進行分析、研究。This dissertation bases on the research of battlefield armored reconnaissance tank system, which is a very important reconnaissance & information reception means for our country ? digital armored troops. the zzco2 radar armored reconnaissance tank system is the collector of radio information by use of the radiation and reflection of electromagnetic wave, at the same time it is a system which saves, processes and transmits the radar information picked up. the content of this dissertation involves the design and development of zzco2 ? software system
本論文以我軍裝甲機械化部隊坦克師的戰場裝甲偵察系統的研製為背景撰寫。該系統是我國數字化裝甲部隊的重要偵察和信息獲取工具。其中zzc02型雷達偵察車(型)是該系統的前沿偵察車,是不可見電磁頻段的雷達信息的收集者,是以電磁波輻射、反射作為信息獲取的主要手段,以計算機主機為中心的信息採集、處理、存儲和傳輸系統。Dsp56f805 samples the ultrasonic pulse coming back from the target, then measures the distance and shows it on led. tms320vc5509a is accomplished the detecting speed and the main control of the radar system, is 16 fixed dsp with high performance and low power produced by ti company. dsp5509a samples the wave coming from t / r module, then measures the target ’ s speed and send this information to the assistant control chip - p89v51 based on boost c51 core mcs produced by philips company, which controls the lcd
測距雷達系統的控制和信號處理的核心晶元是motorola公司的dsp型16位單片機56f805 ,由它對超聲波回波脈沖進行ad采樣后,計算目標距離並在七段數碼管上顯示。測速雷達系統中信號處理的核心晶元是ti公司的超低功耗、高性能的16位定點dsp ? ? tms320vc5509a ,由它對收發組件輸出的多普勒回波進行采樣,計算出目標運動速度后,送給輔助控制晶元? ?飛利浦公司生產的基於c51內核的增強型單片機p89v51 ,並且在液晶顯示器上顯示速度信息。As active and passive radar composite seeking technology balances the tackle performance, design complexity and expenditure of a missile guided system, there will still be great potential of such technologies in current and future theater assault and defense systems
這使該技術在當前及未來的戰場攻防體系中具有很強的應用前景。信息融合演算法設計是主被動雷達復合制導技術的核心,其本質屬于多傳感器多目標融合跟蹤演算法范疇。The assimilation experimentation results indicate that after assimilating radar wind field of small spatial scale, mesoscale and small - scale precipitation prediction can be improved and mesoscale and small - scale information which ca n ' t appear by tradition datum can be gained, which is valuable to analyze the mesoscale and small - scale system structure ; the effect assimilating radar humidity field is n ' t obvious, which is perhaps correlation with precipitation types and assimilating time. the results also show that adding radar humidity field to initial condition at initial time can supply the gap of the regular data in reflecting the mesoscale and small - scale systems, strengthen the humidity in the initial field, and eventually help to improve precipitation. the experiment of assimilating radar wind field and radar humility field at the same time shows that vapor transportation and local vapor divergence play more significant role in causing excessively heavy rain than only high wet center
同化試驗結果表明:同化空間解析度很高的雷達風場后,能改善中小尺度降水的預報效果,並且能夠得到常規觀測資料所不能得到的中小尺度信息,對分析中小尺度系統結構具有重要意義;同化雷達濕度場效果不明顯,可能與降水類型和同化時刻有關;而直接在初始時刻加入雷達濕度場,補充了常規資料在反映中小尺度系統方面的不足,增強了初始場中的水汽,有利於降水量的增加;同時同化雷達風場和雷達濕度場的試驗表明,水汽的輸送和局地的水汽輻合對于產生特大暴雨的貢獻遠大於僅有高濕中心的貢獻。分享友人
