Abstract/Summary
This report covers the design, fabrication, and test of an X-band FMCW radar inspired by the radars from Cal Poly course EE 541, “Advanced Microwave Laboratory.” In this class, 2.4GHz Doppler and FMCW radars are designed and built using consumer off-the-shelf (COTS) components. Operability is the focus of this class, sacrificing performance, accuracy, and precision. this project aims to improve upon those radars by using custom-designed components instead of COTS components and shifting the operating frequency to 10GHz.. The use of custom components can improve output power and frequency stability, and higher frequency reduces component size. The FCC allows amateur operation on bands near 5, 10, and 25GHz. Cal Poly’s equipment (HP8720C VNA) has a 20GHz maximum frequency; hence, 10GHz is chosen for the operating frequency. This project is an exercise in RF design encompassing the entirety of Cal Poly’s RF curriculum. From Cal Poly courses EE 335 and 402, guided and free-space propagation of electromagnetic waves are present everywhere in the system, from synthesis to radiation. Custom amplifiers from Cal Poly course EE 405, as well as antennas from course EE 533 are used. Mixers, oscillators, filters and detectors are inspired by Cal Poly courses EE 440, 502, and 529.
