Challenge Problems
Push your limits with advanced challenges
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.
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.
