CONSTELLATION AND LOCATION ACCURACY ANALYSIS OF MULTISTATIC RADARS BASED ON RANGE DIFFERENCES

摘要: 本文首先給出了基于距離差定位的誤差概率分布;然后根據(jù)誤差協(xié)方差矩陣和兩種常用的定位精度度量準(zhǔn)則關(guān)系,利用最小誤差橢球準(zhǔn)則,給出了在對(duì)稱地面上對(duì)空中目標(biāo)進(jìn)行定位的最優(yōu)布局方法;最后給出了一些計(jì)算結(jié)果.

Abstract: The probability distribution of the location error based on range differences is presented first. After having the relationship between two common criteria for measuring location accuracy and the error covariance matrix, the optimal constellation is obtained for the case in which the radars are constrained in a sysmmetic area to locate a target in space by use of the minimum error ellipsoid criterion. Finally, some calculation results are given.
