Topic: Radar and Navigation
A radar system uses magnetron as high power RF source. Its transmitter emits 300 kW RF power at 10% duty factor. If the efficiency of radar transmitter during pulse is 60% and the power required during pulse off period is 1 kW. The average power dissipation in radar is,
- A. 50.9 kW
- B. 301 kW
- C. 20.9 kW
- D. 150.5 kW
Answer: C. 20.9 kW
Explanation: Based on the official answer key, the correct option is (c). Detailed mathematical derivation is not provided in the reference, but the computation involves calculating the power dissipated during the ON time due to inefficiency and combining it with the power consumed during the OFF time.
