Question 1
What defines angular resolution?
- The maximum angle two targets can be apart
- The minimum angle separation needed to distinguish targets
- The distance between two targets
💡 Hint: Consider how radars differentiate targets based on angles.
Question 2
True or False: Increasing the antenna aperture improves angular resolution.
- True
- False
💡 Hint: Think about how 'larger' changes the narrowness.

Challenge Problems
Push your limits with challenges.
Question 1
A radar system operates at 2.5 GHz with an antenna aperture of 2m. Calculate the half-power beamwidth and determine if it can distinguish between two targets at the same range if they are 0.5 degrees apart.
💡 Hint: Break down the problem step by step, starting with wavelength.
Question 2
If increasing the antenna size to 4m can reduce beamwidth to improve tracking in dense environments, estimate the enhancement in angular resolution compared to a previous 2m antenna operating at the same wavelength.
💡 Hint: Model how aperture size affects beamwidth and angular resolution practically.
