According to AWST, J.H. Poynting was on to something ...
"The technological walls separating radar, electronic warfare and missile defense are coming down. This fundamental shift has resulted in development, not yet publicly acknowledged, of multifunction, active electronically scanned array (AESA) radars that can locate stealthy airborne targets and then jam their computers and guidance systems with at least enough effect to drive them off course by using a focused beam of X-band radar energy."
