| 摘 要： | 数字信道化接收机是一种新型接收机,非相干积累的时频短时傅里叶变换,能有效地增加接收机的处理增益和对非平稳信号的截获能力,从而提高数字信道化接收机的整体检测性能。该文就其虚警检测问题展开分析,获得了给定虚警概率下的单信道虚警检测门限,并进行了仿真验证,进而为工程中的实际应用提供了有效的理论支持。

| Abstract: | The analysis of time-frequency short time Fourier transform(STFT) based on noncoherent integration can increase the processing gain of the receiver and its capability of intercepting the nonstationary signals effectively,thus improving the detection performance of the system.The paper deals with the threshold of false alarm detection by a single channel under a given false alarm rate(FAR).Both mathematic analysis and simulation are carried out.This study provides an effective theoretic support for practical application. |

| Keywords: | channelized receiver noncoherent integration time-frequency short time Fourier transform detection threshold |
