| 摘 要： | 目标源设置于海面渔网上，向周围海域全向辐射f=2.45GHz的微波信号，跟踪搜索系统位于船上，通过转动天线接收目标源发出的信号，可探测半径为10km范围内渔网的方向和位置。系统中采用了锁相技术和地址编码，并采用间隙工作方式，使得本系统工作性能稳定，目标源一次充电可连续工作10天以上。

| Abstract: | A tracing system placed on fishing boat to search for active target which
placed on fishing net floating over sea. The target isotropy radiates f=2.45GHz microwave
coding signal. Tracing system detect the target's distance and direction through the
amplitude of received coding signal and the direction of receive antenna. The effective
range within 10km. Phase-lock oscillator, address coding and intermission mode are taken
to stabilize the system and to promise the target's working period longer than 10 days
after its source charged. |
