Question

A parabolic radar antenna with a 2-m diameter transmits 100-kW pulses of energy. If its reptition rate is 500 pulses per second, each lasting 2 ms, determine the average reaction force on the antenna.

Expert Solution

Step 1: Data given from the Question

Power ( $P$ ): 100 kW (which is equivalent to $100 cross times 1 0 cubed$ W)
Pulse duration ( $t$ ): 2 ms (which is equivalent to $2 cross times 1 0 to the power of negative 3 end exponent$ s)
Repetition rate ( $f$ ): 500 pulses/second
Speed of light ( $c$ ): $3 cross times 1 0 to the power of 8$ m/s

These values were used to calculate the average reaction force on the antenna.
