Thesis (MScEng (Electrical and Electronic Engineering))--University of Stellenbosch, 2008. / Modern technology is reducing the cost of electronic devices. The speed of
these devices and their reliability is improving. They can be used to implement
low cost systems without compromising performance.
The design of two linear FM-CW radars using direct digital synthesis
(DDS) is discussed. The use of the DDS simplifies the generation of the linear
frequency sweep that is required. The systems are analysed mathematically
and by computer simulation, before being implemented in hardware.
The first system is to be used to measure the position of pedestrians, at
short range. The other system is to be used as a ground penetrating radar to
measure the depth of objects located close to the surface.
The design of a micro-strip patch array with a corporate feed network is also
discussed. The antenna is constructed, measured and used in the pedestrian
measurement system.
Both systems are tested and used for initial radar measurements and the
results obtained are presented.
