Abstract
In the current literature, ultra-wideband (UWB) waveforms are said to possess several potential advantages such as penetration of foliage, walls and ground, as well as target identification and detection of stealth targets. Due to the potential advantages of UWB waveforms, UWB power sources are currently being developed. This thesis investigates the Fourier synthesis method of waveform generation which is to be used with ultra-wideband radar. The major advantages of this method over traditional methods are that accurate control of pulse shapes and pulse repetition intervals (PRI) can be generated. In this thesis, the Fourier method is extended to generation of binary coded waveforms for UWB systems. The generation of such codes is important as it allows for the use of longer coded pulses. These coded pulses contain more energy and improve signal to noise ratio (SNR) while still retaining the range resolution and other benefits of smaller pulse widths.
