摘要: 利用無源傳感器對輻射源進(jìn)行無源定位是重要的研究課題,受到廣泛重視。而利用運(yùn)動的單一傳感器對運(yùn)動的多個輻射源同時進(jìn)行運(yùn)動狀態(tài)分析則是無源定位問題中的難點(diǎn)。狀態(tài)空間模型可將輻射源的參數(shù)估計和輻射源的運(yùn)動狀態(tài)分析有機(jī)地聯(lián)系在一起。本文基于狀態(tài)空間模型和運(yùn)動的單一均勻線陣,用信息論準(zhǔn)則和ESRPIT算法對輻射源的個數(shù)、輻射源的發(fā)射頻率和空間頻率、空間頻率變化率進(jìn)行聯(lián)合估計,進(jìn)而對各個輻射源進(jìn)行運(yùn)動狀態(tài)分析(TMA目標(biāo)運(yùn)動分析)。

Abstract: The passive location is a key in many applications. It is a difficult question to estimate trajectories of multiple moving sources with single moving station. This paper deals with the estimation of motion parameters of multiple sources in the passive array processing. It uses basically state-space model of the spatial-temporal data. The interpolation signal procedures play a fundamental role and link the spatial and temporal analysis. Using uniformity linear array and MDL and ESPRIT algorithms, the numbers, center frequencies of sources, spatial frequency and spatial frequency change speed can be estimated together. Further the trajectories (i.e., position and velocity) of every source can be estimated. -
