Abstract: |
To simplify the algorithm of single-observer passive location based on
outer radiant point, the polar coordinate model is built. The algorithm based o
n nonlinear least square(NLS) algorithm is presented in polar coordinate. To red
uce the computati
on complex of NLS algorithm,a low-complexity suboptimal algorith
m is proposed. The simulation results demonstrate the location precision and sta
bilization of the suboptimal algorithm, which provides reference for engineering
realization. |
