In a pulsed radar set, the function of the duplexer is to

Allow the transmitter and the receiver to operate from a common antenna

Aid in calibrating the display unit

Prevent frequency drift in the klystron

All of these

The antenna separations (in meters) required for optimum operation of a space diversity system can be calculated from:where R = effective earth radius (m) and L = path length (m)

S = λR/L

S = 2λR/L

S = λR/RL

S = 3λR/L

S = λR/L

S = 2λR/L

S = λR/RL

S = 3λR/L
