The receiver test procedures are used to determine the performance of an EW receiver. Although the detailed performance of an EW receiver is difficult to measure, because of the wide frequency bandwidth and high dynamic range the receiver covers, the measurement procedures discussed in this chapter will provide an overall performance evaluation of an EW receiver. In general, if a deficiency is discovered in a certain receiver, a detailed evaluation should be performed so that one can understand the causes of the deficiency and generate solutions to correct it. After all, a receiver is like a human being. There is no perfect person, and there is also no perfect receiver. One can always choose certain input signal conditions to make a receiver produce erroneous data or miss signals, even if the receiver is only a paper design.
