As is evident from this chapter, radar electronic warfare (EW) includes a wide range of methods by which adversary electronic attact (EA) and electronic support (ES) systems can degrade or exploit radar operation. The EA effects primarily consist of masking and deception and provide screening of targets through either support jamming or self-protection jamming deployments. Jamming is generated through either coherent or noncoherent EA system architectures: the former can preserve the phase information of the radar, the latter cannot. There are numerous EA techniques, operating in the range, Doppler, or angle dimensions of the radar, including noise, false targets, and track gate stealing. Table 12-3 lists the EA techniques mentioned briefly in this chapter, along with their intended effect, jammer type, and jammer role. There are numerous variations to forming such a list, but this provides a representative example of the diversity of EA options.
