摘要
在运用阴影逆合成孔径雷达(SISAR)对运动目标进行成像和识别研究中,需要得到相关目标的全息信号。该文在分析目标侧影轮廓与其全息信号关系的基础上,导出了一种更具普遍意义的全息信号的表达形式,式中的各组成具有明确的物理含义。为验证其在实际应用中的有效性,以外场试验获得两种目标的全息信号为比较对象,参照外场试验条件进行了仿真。比较结果说明了该仿真方法实际有效。
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 generalized 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.
