滑窗 meaning in Chinese
sliding window
Examples
- A high - speed data acquisition and storing system , which is based on sata disks and used in sar , is introduced in this dissertation . fpga is used to control the system ’ s working time
文中提出了一种基于滑窗的回波检测方法,并设计、实现了一种应用于sar 、基于sata硬盘的高速数据采集和存储系统。 - But its detection performance is not so good under multiple targets situation . the mgo - cfar detector ' s detection performance degrades dramatically when there is one interfering target in the reference window
但在多目标环境中的检测性能较差，当参考滑窗中有一个干扰目标时， mgo - cfar的检测能力就已经严重下降。 - The primary work in this dissertation : a method was present to detect the radar echoes by slide - window . the calculation of gate , which was based on cfar , was present and proved both by theory and experiment result
本文主要工作如下: 1 、提出了一种通过滑窗检测的方法实现对雷达回波的检测,并基于恒虚警处理技术提出一种检测门限的计算方法,从理论推导和系统测试结果对其进行了验证。 - In the forth and back windows , the mosos - cfar detector uses the ordered statistics as the background cutter power level of the two windows , and the sum of the forth and back local estimation as the total estimation of background clutter power level
Mosos - cfar检测器在前后滑窗分别采用有序统计量来表示前后滑窗的背景杂波功率水平，再将前后局部估计相加作为总的背景杂波功率水平估计。 - ( 4 ) after factual characteristics of targets and clutter have been studied , an approach of radar signal detection based on factual has been given and analyzed deeply , the influence caused by different window length , signal to clutter ratio ( scr ) and clutter background has been analyzed , then the monte - carlo simulation method has been used to analyze the detection performances
( 4 )研究了目标和杂波的分形特性,深入研究了基于分形的雷达信号检测方法,分析了不同滑窗长度、不同信杂比和杂波背景变化情况对回波分形维数的影响,采用蒙特卡罗仿真分析该检测器的性能。
