Q

What is the distance in nautical miles to a target if it takes 308.5 microseconds for the RADAR pulse to travel from the RADAR antenna to the target and back.

🔍 Key Concepts

• Radar range formula based on time for the pulse to travel to the target and back • Conversion between microseconds and seconds • Speed of radio waves/radar pulses is approximately the speed of light in meters per second, and then converting meters to nautical miles

💭 Think About

• How do you find the one-way distance to the target if the time given is for the pulse to go to the target and back? • Once you compute the distance in meters using time and speed, how do you convert meters to nautical miles? • After you calculate the approximate range, which of the answer choices is closest to your result?

✅ Before You Answer

• Be sure you divide the round-trip time by 2 to get the one-way travel time to the target. • Confirm the conversion: 1 nautical mile ≈ 1852 meters. • Carefully convert microseconds to seconds before using the speed of light in m/s.
