摘要 舰艇编队内同型雷达间的同频干扰本质上属于舰艇编队内部的电磁兼容问题。为使编队中各舰的同型号雷达能够一起工作,必须有效消除同频干扰。首先讨论了消除同频干扰的一般方法,然后针对非相参体制的雷达,设计了一种消除抗同频干扰装置,通过增加雷达重复周期,将同频干扰变为异步干扰,再用反异步信号处理进行对消。海上验证试验表明,这种方法能够有效消除编队内同型号雷达之间的同频干扰。 Essentially, the shared-frequency jamming between shipborne radars is of an electromagnetic compatibility within the warship formation. The shared-frequency jamming must be cancelled to ensure the shipborne radars of the warship formation operate cooperatively. A general method for canceling the shared-frequency jamming is described firstly. For incoherent radars, a device against shared-frequency jamming is developed, which increases the PRF, changes the shared-frequency jamming into asynchronous jamming, and then cancels the jamming by using the anti-asynchronous signal processing method. Experiments on the sea show that this method can effectively cancel the shared-frequency jamming between same types of shipborne radars for the warship formation.
