Abstract
The study presented in this article belongs within the context of a design of a new kind of short-range Ultra Wide-Band (UWB) Radar with an autonomous scanning capability. The generation of short pulses is performed with an optoelectronic device triggered by a laser flash and operating in linear switching mode. By adding as many optical systems as antennas, we create a transmitting array with increased radiated energy. Each of those elements are fed with bursts composed of UWB optogenerated pulses with a slightly different pulse repetition frequency allowing beam-scanning capability. This article presents in detail all the parts needed to implement the elementary radiation source and offers a mathematical method of calculation to trace back to the generated feeding signal.
