| 摘 要： | 雷达对抗已成为雷达领域的重要课题,雷达的抗干扰性能愈发重要。该文提出了跟踪雷达的高重频随机跳频体制,该体制能消除"二次"回波,并具有较高的距离和速度分辨力。该文分析了高重频随机跳频跟踪雷达对抗欺骗干扰的性能,得出的结论是:由于发射频点随机跳变,对该雷达体制有效地欺骗干扰必须是转发式的;该雷达体制能对抗转发延迟大于脉宽、或者干扰信号功率不足以掩盖真实回波的转发式欺骗干扰。计算机仿真结果符合上述分析结果。

| Abstract: | Radar countermeasures have become an important issue with the anti-jamming methods needed in radar systems.This paper describes a high pulse repetition frequency(PRF) tracking radar with random frequency hopping which eliminates multiple repeat echoes with both long range ability and good velocity resolution.Simulations show that the system is able to counter deceptive jamming methods with the hopping transmission frequency,effective deceptive jamming of this radar system must come from a repeater.The radar... |
