چکیده

In order to launch different receivers in electronic warfare, side-circuits are required to detect the presence of a pulse at the receiver input and to report it after making sure that the receiver output is not due to system noise alone. In practice, a crystal video receiver (CVR) is used for this purpose. This receiver provides the required time information (or domain related information) to the other part of an electronic warfare receiver by extracting the received RF signal wave envelope. In this paper, after a conceptual overview of the structure of this receiver, the analysis of its function (sensitivity) will be dealt with. Moreover, some important issues in its design will be discussed. In addition, since the IFM and CVR receivers are not capable of processing simultaneous pulses or pulses coupled with the CW, some further steps are taken to maintain system efficacy under such conditions.
