本文提出了一种新的非搜索法测频接收机变型电路。在此接收机中利用高频信号的调相方法来减少滤波器数目。它只用(m+n)个滤波器,就可得到具有m×n个滤波器的一般分路测频接收机的频率分辨率。通过一个数值例子可以证明:它的性能胜过矩阵式接收机。
In this paper, a new non-search method frequency measurement receiver variant circuit is proposed. In this receiver the use of high-frequency signal phase modulation method to reduce the number of filters. It uses only (m + n) filters to get the frequency resolution of a typical shunt frequency receiver with m × n filters. A numerical example proves that it performs better than a matrix receiver.
