Performance Analysis of AOA-Based Localization Using the LS Approach: Explicit Expression of Mean-Squared Error

Abstract EN

In this paper, a passive localization of the emitter using noisy angle-of-arrival (AOA) measurements, called Brown DWLS (Distance Weighted Least Squares) algorithm, is considered.

The accuracy of AOA-based localization is quantified by the mean-squared error.

Various estimates of the AOA-localization algorithm have been derived (Doğançay and Hmam, 2008).

Explicit expression of the location estimate of the previous study is used to get an analytic expression of the mean-squared error (MSE) of one of the various estimates.

To validate the derived expression, we compare the MSE from the Monte Carlo simulation with the analytically derived MSE.
