RECEIVER TYPES AND CHARACTERISTICS
Besides the considerations of noise and noise figure, the capabilities of receivers are highly dependent
on the type of receiver design. Most receiver designs are trade-offs of several conflicting requirements. This is
especially true of the Electronic Support Measures (ESM) receivers used in Electronic Warfare. This section
consists of a figure and tables that provide a brief comparison of various common ESM receiver types. Figure 1
shows block diagrams of four common ESM receivers. Table 1 is a comparison of major features of receivers. Table 2
shows the receiver types best suited for various types of signals and Tables 3 and 4 compare several direction of
arrival (DOA) and emitter location techniques. Table 5 shows qualitative and quantitative comparisons of receiver
characteristics.
