中文摘要：
在通信对抗中,对目标跳频信号进行有效检测是对该信号进行后续处理及实施干扰的前提,利用信道化检测方法实现对跳频信号的盲检测。侦察方作为通信非协作接收者,无法与目标信号发送端实现时间同步,导致信道化检测方法性能不佳,针对此问题,提出一种简单高效的判决门限改进算法。仿真结果表明：采用改进算法,虚警概率显著降低,在信噪比大于-2 dB时检测概率有一定的提高。最后给出了关于进一步提高信道化检测方法性能的几点策略。
英文摘要：
In the communication countermeasure,the effective detection of the target Frequency-Hopping signal is the groundwork？ of interference with it, This paper use the channelized method to achieve it.Refer to the unoptimizable detection performance which is caused by the reconnaissance could not synchronize with the target signal transmitter.Bring forward a improved algorithm to calculate the threshold in this method.The simulation results show that this improved method is effective and viable.Give several tactic about how to much more improve the performance of this method.
