20. A shipboard RADAR transmitter has a pulse repetition frequency (PRF) of 1,000 Hz, a pulse width of 0.5 microseconds, peak power of 150 KW, and a minimum range of 75 meters. Its duty cycle is:
Duty cycle is calculated by multiplying pulse width (converted to seconds) by the pulse repetition frequency. Converting 0.5 microseconds to seconds and multiplying by 1000 Hz yields 0.0005.
