The very success of radar at detecting and tracking military targets means that it has become the target of electronic attack itself. As soon as a military radar system is turned on, its EM emissions will be detected unless it uses spread spectrum LPI techniques to evade detection. Any radar signals detected will be analysed by ESM receivers and an ECM strategy formulated; this may include the use of Stealth to reduce the RCS of the target. While electronic countermeasures are effective, and expensive to defend against using ECCM techniques, the balance at present probably resides on the side of radar, provided the waveforms are controlled intelligently.
