| 摘 要： | 窄带电子侦察接收机具有能够稀释信号和便于实现数字处理等优点,通过对宽带信号在窄带接收机中的过渡过程的分析,证明了宽带信号经过窄带系统后,其方位信息得到了保存,并且测向算法的设计与通频带带宽及阵元相对位置等系统指标有关。结合MUSIC算法完成了方位信息的提取并进行了计算机仿真实验,证明了结论的正确性。

| Abstract: | Narrowband electronic reconnaissance system has the advantage of reducing signals and is convenient for digital processing.By analyzing the process of wideband signal passing narrowband receiver,it can be proved that the direction information of wideband signal is kept after passing the narrowband system.And it can also be proved that the design of direction finding algorithm is related to the specifications of the system,such as passband bandwidth and the position of the sensors.Computer simulation experiments with MUSIC algorithm demonstrate the above conclusion is corrective. |
