Summary

ECE480 senior design project.  This radar system creates a UWB impulse of 2nS in duration.  The impulse is created by clipping a Mini-Circuits MMIC amplifier, then high-pass filtering the output with a 600 MHz 5th order Butterworth.  The output of the pulse generator is fed into a mixer, up converted to 2 GHz, amplified to 80 mW peak power, then radiated towards a target scene.  Received RF is coherently converted down to base-band the same way, then digitized using a random sampling scope.
