Examples
- So far , there has not been a mature signal detection approach for hrr radar signals yet
迄今为止,还没有一种成熟的高距离分辨雷达信号检测方法。 - The rangeprofile can be formed by high - range resolution radar ( hrr ) . the rangeprofiles of the targets contain more information for recognition than the radar cross section ( rcs )
使用高距离分辨率雷达可获得目标的一维距离像,一维距离像包含了更多的可用于目标识别的信息。 - Due to the targets and clutter ’ s specific characteristics of hrr radar , there are several new technical problems in signal detection , such as the detection under the unrayleigh clutter background
由于高距离分辨雷达目标和杂波回波的特殊性,信号检测也存在一些新的技术问题,如非瑞利杂波背景下的扩展目标检测问题。 - In this dissertation , radar detection in hrr has been taken as background . the followings are main contents of this dissertation : ( 1 ) based on analyzing the targets and the clutter ’ s specific characteristics of hrr radar , the echo models of targets and clutter have been studied respectively ; the changes of targets ’ echoes in different elevation angles , azimuth angles and attitude angles have been analyzed ; then , the echo models of lfm radar clutter have been established
本文针对高距离分辨雷达目标检测开展研究,主要完成了以下几方面的工作: ( 1 )分析了高距离分辨雷达目标和杂波回波特征,在此基础上分别研究了高距离分辨雷达目标和杂波的回波模型,分析了不同俯仰角、不同方位角以及不同姿态下目标回波模型的变化,并建立了线性调频脉冲压缩雷达的杂波模型。 - After finished the comprehensive analysis , the paper use a demonstration to validate the contents and analysis framework . the demonstration researched the validity and feasibility of 200 ktpy soda ash project that be invested by hrr group in jiangsu to realize forward integration by cost leadership
