摘　　要：本文结合某型号相控阵雷达信号处理器的研制,从工程应用的角度出发,提出了一种基于MTD中间滤波器噪声统计的噪声电平恒虚警方法,该方法旨在保持系统的虚警概率相对恒定的条件下,使得系统的检测损失较小。工程实践表明,该方法有效可行。A method of noise level constant false alarm based on statistical MTD intemediate filter noise is presented combining with development of signal processor of a type phased array radar and starting from point of engineering application view. This method is intended to make detection loss of the system minimum under condition of keeping false alarm probability constant relatively. Then practical project shows that effectiveness and feasibity of the method.
