Desirable Qualities of RADAR System (General Requirements of RADAR)

A RADAR (Radio Detection and Ranging) system should have the following qualities (General Requirements of RADAR)

• The transmitted pulse by the radar transmitter should be powerful enough to counter the attenuation (losses) during forward or return Journeys.

• The radar transmitter should remain silent during the echo period.

• The receiver should be extremely sensitive and also immune to noise signals since signals are very weak.

• Directivity of the antenna of the radar should be high. Directivity of antenna is a basic parameter, that is the measure of degree to which the radiation emitted by the antenna is the focused in a particular direction.

• The gain of antenna should also be high as it is required to transmit strong signals.
