摘要: 在運(yùn)用陰影逆合成孔徑雷達(dá)(SISAR)對(duì)運(yùn)動(dòng)目標(biāo)進(jìn)行成像和識(shí)別研究中,需要得到相關(guān)目標(biāo)的全息信號(hào)。該文在分析目標(biāo)側(cè)影輪廓與其全息信號(hào)關(guān)系的基礎(chǔ)上,導(dǎo)出了一種更具普遍意義的全息信號(hào)的表達(dá)形式,式中的各組成具有明確的物理含義。為驗(yàn)證其在實(shí)際應(yīng)用中的有效性,以外場(chǎng)試驗(yàn)獲得兩種目標(biāo)的全息信號(hào)為比較對(duì)象,參照外場(chǎng)試驗(yàn)條件進(jìn)行了仿真。比較結(jié)果說(shuō)明了該仿真方法實(shí)際有效。Abstract: The simulation of radio holographic signal for moving objects acts an important role in the study of the target imaging and recognition in the research of the SISAR. A gener-alized expression is induced on the basis of analyzing the relation between the shadow of the moving target and its radio holographic signal. Further, each component in the expression has explicit physical signification. The validity of the method is shown by the comparision of the simulation results with the experimental results of two air moving targets in the same condition.
