Is there a difference between radar antenna and normal antenna?

Can anyone tell me the difference between a normal antenna and a radar antenna
and what are the principal radar antenna functions ?

How do we feed a radar antena, does the antenna system contain any power unit which feeds DC or AC power ?

Regards,
Avi

there is no difference, the same antenna has a transmitter and a receiver attached, pretty much regardless of if its a large dipole antenna at VHF or a horn fed parabolic reflector at microwave freqs or whatever other variation in between.

On a very basic level the transmitter is pulsed rapidly and the receiver usually muted during those pulsed so as not to be swamped by the hi power level. The receiver is turned on/unmuted between the TX pulses so that it can "listen" for the reflections of the transmitted pulses.

cheers
Dave
