A pulse RADAR transmits a 0.5 microsecond RF pulse with a peak power of 100 kilowatts every 1600 microseconds. This RADAR has:

🔍 Key Concepts

• Pulse Repetition Interval (PRI) vs Pulse Repetition Frequency (PRF) and how they relate: PRF = 1 / PRI • Duty cycle for a pulse RADAR: duty cycle = pulse width / PRI • Average power for pulsed transmitters: average power = peak power × duty cycle

💭 Think About

• Convert both the pulse width (0.5 microseconds) and PRI (1600 microseconds) into seconds before doing any calculations. What does that do to your PRF and duty cycle values? • Once you find the duty cycle as a decimal, how do you express it as a percentage, and how does that compare to the duty cycle answer choice? • Use your duty cycle and the peak power (100 kW) to find the average power. Does any answer choice match that computed average power?

✅ Before You Answer

• Be sure you are using seconds, not microseconds, in your PRF and duty cycle formulas. • Confirm that PRF and unambiguous maximum range are inversely related: higher PRF → shorter maximum range. • Verify that the duty cycle percentage in the answer choices is consistent with your computed duty cycle (decimal × 100).
