Aim

This project aims to implement a portable Radar transceiver capable of measuring a target's range and radial velocity. The transceiver shall be implemented into a PCB (Printed Circuit Board) containing RF and analogue subsystems and audio input/output to a computing system for processing and display. The system shall have a range resolution smaller than 2m and a range of approximately 100m for a target with a radar cross section of 1m squared.

Conclusion

This thesis outlines the steps taken to design a portable Radar system into a PCB based implementation. The objective characteristics were a range resolution smaller than 2 and a range of approximately 100m for a target with a radar cross section of 1m^2

Through the analysis of different radar architectures and waveforms a stretch processing system was decided upon.The designed system had a theoretical range resolution of 1.764m and a maximum range of 100m.

Although the system was deemed not operational at completion, the transmitter system was operational, tested and voltage waveforms designed for its use. The fabricated system had increased portability comparing to previous works outlined in.

Although the manufacture objectives of the project were not met, the design objectives were and further work and manufacture of PCB design 2.0 will result in an operational system with the referenced above characteristics.
