DF—Ⅱ型车载无线电监听测向系统是南京新兴电子系统公司最近研制成功的新一代高科技电子侦察系统,是机电一体化设计的一个典型范例。该系统是车载的移动式无线电电子侦察设备,主要用于搜索截获不明无线电辐射信号,并对其进行追踪定位。全方位频率搜索、监听识别、即时测向、全频谱信号监视、频谱信号分析并正确引导载车抵近目标辐射源位置是DF—Ⅱ系统的基本工作模式。DF—Ⅱ系统对监听灵敏度、测向精度、测向速度及信号数据综合处理能力提出了更高的要求。其主要设计指标为:
DF-Ⅱ car radio monitor and direction finding system is a new generation of high-tech electronic reconnaissance system recently developed by Nanjing Xinxing Electronic System Co., Ltd. It is a typical example of mechatronic design. The system is an on-board mobile radio electronic reconnaissance equipment, which is mainly used for searching for intercepted signals of unknown radio signals and tracking them. Full range of frequency search, monitoring and recognition, real-time direction finding, full spectrum signal monitoring, spectrum signal analysis and correct guidance of the vehicle to the target radiation source is the DF-Ⅱ system’s basic mode of operation. The DF-Ⅱ system puts forward higher requirements on the monitoring sensitivity, direction finding accuracy, direction finding speed and signal processing capability. The main design indicators are:
