脉间波形变换信号分选跟踪器的设计与实现

Design and implementation of sorting and tracing device for various waveform radar signals

针对目前普遍存在的LPI雷达信号识别截获难的情况,提出了一种脉间波形变换信号的分选跟踪器的设计方案．在多脉宽和捷变分析的基础上,采用了改进的概率统计算法和动态关联扩展法进行分选,在跟踪器中采用了“多波门”和“少波门”2种波门给出方式,并进行了软硬件设计和测试．实践证明,此分选跟踪器对于脉间波形变换信号有着较强的识别能力．

Considering the difficulty in LPI radar signal interception, a new sorting and tracking device is proposed based on various waveform radar signals, and the principle for different parts of the device is given. On the foundation of the analysis of multi-PW （ pulse width） and agile frequency radar signals, the improved probability statistics algorithm and dynamic correlative expansion method are adopted to sort radar signals, and the wide-gates are given by two ways： the ＂multi wide-gates＂ and the ＂less wide-gates＂. The software and hardware design and the test are also done. It has been proved that this new sorting and tracking device has better identification ability for various waveform radar signals.
