Abstract
This project presents circuits necessary to create a mobile Continuous Wave Doppler radar for fall detection. A radar as an assistive device for the elderly will solve the main problem with current marketed devices because a radar does not require user interaction. Currently, most radars are large and are not practical for mobile use. The project involves design, fabrication, and testing of an oscillator, antennas, an amplifier, a power splitter, a mixer, and a low pass filter. The end products are components with sizes ranging from one inch by one inch to one inch by three inches, which makes it feasible to construct the mobile radar.
