摘　　要：在最大选择恒虚警率（GO-CFAR）雷达信号检测方法的基础上提出了一种应用于塔康（TACAN）信号的检测技术,它采用前后滑窗单元平均产生噪声估计,再对二者进行比较取最大值实现对目标信号的检测,从而代替了传统塔康检测中的固定门限设置。在均匀高斯白噪声背景下,得出了塔康信号的检测概率、虚警概率和平均判决阈值的解析表达式。使用SIMULINK建立了系统仿真模型,对该方法进行了验证。分析结果表明,该技术具备较好的塔康信号检测性能。A new TACAN signal detection technique based on Greatest- Of （GO） CFAR Radar signal processing is proposed in this paper. The maximum of sample means between leading and lagging sets of cells is taken as the noise estimation rather than predefined threshold for signal detection. Under the homogeneous background of Gaussian white noise, the analytic expressions of detection probability, false alarm probability and average decision threshold are acquired. In order to verify this technique, the system simulation model is established by SIMULINK. The results show that this technique performs good in TACAN signal detection.
