【摘要】：針對傳統(tǒng)的僅測脈沖到達(dá)時(shí)間(TOA)定位方法不能適應(yīng)復(fù)雜體制雷達(dá)信號的問題,提出了一種新的基于TOA測量的位置信息場定位算法。首先由主站自提取輻射源的脈沖樣本圖,副站利用主站自提取的脈沖樣本圖匹配分選出該站接收的輻射源脈沖列,并將其對應(yīng)的TOA數(shù)據(jù)傳回主站,而后由主站基于各站的TOA測量構(gòu)造目標(biāo)位置信息場函數(shù),通過網(wǎng)格搜索法實(shí)現(xiàn)對輻射源位置的估計(jì)。仿真結(jié)果驗(yàn)證了該方法的有效性。
[Abstract]:In order to solve the problem that the traditional (TOA) localization method with only measured pulse arrival time can not adapt to the radar signal of complex system, a new location algorithm based on TOA measurement is proposed. First, the pulse sample map of the emitter source is extracted by the master station. The secondary station uses the pulse sample map extracted by the main station to match and select the pulse sequence of the emitter received by the station, and the corresponding TOA data are transmitted back to the main station. Then the target location information field function is constructed by the TOA measurement of the main station and the location estimation of the emitter is realized by the grid search method. Simulation results show the effectiveness of the method.
