In passive radio electronic intelligence, to identify and separate sources of radio emissions with a frequency range from hundreds of megahertz to tens of gigahertz, hybrid wideband receivers for instantaneous measurement of the carrier frequency of the input microwave signal are used. In these receivers both analog algorithms for determining the carrier frequency based on frequency discriminators, and digital algorithms based on the fast Fourier transformation are realized. In this case, the breakdown of a wide input frequency range into subranges leads to an increase in the number of receivers. In the means of passive radio electronic intelligence, the number of receivers is estimated at the tens. The organization of work on manual adjusting, monitoring of the accuracy characteristics of manufactured receivers leads to an increase in the deadline for their production, a decrease in their quality and reliability, and also significantly increases the overall labor costs and the cost of producing receivers. To improve the quality and reliability of receivers, as well as to reduce the time and cost of their production, it becomes necessary to automate the process of adjusting, monitoring and evaluating the accuracy characteristics of receivers for instantaneous measurement of the carrier frequency of microwave signals using a software-hardware complex. To create a software-hardware complex for adjusting, monitoring and evaluating the accuracy characteristics of receivers for instantaneous measurement of the carrier frequency of microwave signals in a wide range of operating frequencies. To develop and manufacture a software-hardware complex for adjusting, monitoring and evaluating the accuracy characteristics of receivers for instantaneous measurement of the carrier frequency of microwave signals in a wide frequency range and conduct its acceptance tests. Put into operation a hardware-software complex for adjusting, monitoring and evaluating the accuracy characteristics of receivers for instantaneous measurement of the carrier frequency of a microwave signal with an evaluation of the accuracy of measuring the carrier frequency of microwave signals by the receiver in a wide frequency range.
