Transient Waveforms Shaping for Frequency Diversity Radar Applications

In this paper, we present a new design of optoelectronic system for transient shaping with a selection of rejected frequencies. The generation of short pulses is performed by several optoelectronic devices triggered via a laser flash. Photoconductive Semiconductor Switches (PCSS) operating in linear switching mode have been used. By using the appropriate number of optoelectronic generators, we create a spectrum ranging from 300MHz to 3GHz, with rejected frequencies at 900MHz and 1.8GHz.
