Stealth tactics

Stealthy strike aircraft such as the F-117 are usually used against heavily defended enemy sites such as Command and Control centres or surface-to-air (SAM) batteries. Enemy radar will cover the airspace around these sites with overlapping coverage, making undetected entry by conventional aircraft nearly impossible. Stealthy aircraft can also be detected, but only at very short ranges around the radars, so that for a stealthy aircraft there are substantial gaps in the radar coverage. Thus a stealthy aircraft flying an appropriate route can remain undetected by radar. Most low rcs radars exploit Doppler filter to increase the SNR, knowing the exact location of the radars enables to design a flight path that has zero radial speed, therefore invisible. Note that in order to be able to fly these "safe" routes, it is necessary to understand the enemy's radar coverage - see Electronic Intelligence. Also note that if the enemy has mobile radars, such as AWACS, this can complicate matters.
