宽带干扰噪声频谱接收技术研究

Study on the Receiving Method of Broad Noise Jamming

针对远距离和随队电子支援噪声干扰的影响 ,防空体系警戒雷达和搜索雷达必须对噪声干扰的频谱进行宽带瞬时侦收和分析 ,在此基础上采取有效的抗干扰措施。对宽带噪声干扰频谱接收技术进行了研究 ,提出了一种瞬时、宽开、灵敏度高。

Early warning radars and searching radars of an air defense system must reconnoiter and detect the jamming signals instantly, which generated by hostile ECM forces, to take efficient electronic counter-countermeasures. Based on this point, a new kind of receiver named channelized receiver detecting jamming signals' spectrum is introduced. This receiver has the proprieties of instant, windband, high sensibility, and large lineal dynamic range.
