| 摘 要： | 瞬时测频接收机性能最基本的要求就是测频精度，而空问内的各种非接收信号的电磁辐射源和由于各种反射体引起与接收信号路程差的反射信号等噪声信号，对瞬时测频接收机的测频精度和频率的分辨力的性能有着不可忽视的影响，并且这种影响具有不确定性。本文着重分析了噪声对瞬时测频接收机测频误差、系统的灵敏度及接收机的虚警概率和探测概率所造成的影响。

| Abstract: | The basic requirement of instantaneous frequency measurement (IFM) receivers is the frequency discrimination precision. The precision is influenced by the electromagnetism radiation source of several non-receiving signal and the glint signals resulted from all kinds of reflectors, leading to indeterminacy. The study focuses on the hindrance of noise on IFM receivers in the following aspects: failure, sensitivity of system, virtual alarm signal probability and detection probability. |
