摘　　要：卫星转发器本地振荡器频率的测量对了解卫星的转发器信息,实现干扰源的定位具有重要意义。本文提出一种通过向卫星发射位于噪底以下的扩频信号,并对经过卫星转发的扩频信号与本地扩频信号进行相关运算处理,从而测量卫星转发器的本振频率的方法。实际测试结果表明,这种方法的测量准确度高,能够达到实际工作的需求。Measurement of the satellite oscillator frequency of the transporter of satellite is of great significance to the understanding of information from the transporter of satellite and to the locating of satellite interference. This article presents a method of measuring the oscillator frequency of the transporter of satellite： direct-sequence spread spectrum signals under the noise f loor are sent to satellites and the correlation between the signals transmitted by satellites and the local counterparts is worked out. Test results have suggested that measurement obtained through this method is highly accurate and meets practical requirement.
