Low frequency radar for improving radar cross section

Stealth or lower visibility is an inevitable feature of future-generation aircraft. A stealth aircraft is coated with a special type of material called radar absorbing material (RAM), which makes the aircraft invisible to radar. Stealth technology is a great threat to the Radar surveillance system. Anti-stealth radar can be built using low-frequency signals that are efficient in detecting stealth aircraft. The variation of radar cross section (RCS) under low frequency radar system is studied here also designed an antenna for low frequency radar.
