Managing the spectrum of radar emissions, particularly from shipboard radar platforms, is critical for minimizing interference to neighboring communication systems on ships, on land and other in-band radars. New radar waveform designs are needed to confine the radar transmitted spectrum to a region separate from other bands that are in use. An out-phasing technique (first developed by H. Chireix) is one approach that was implemented in hardware that provides a means of generating spectrally confined radar waveforms. A series of experiments were conducted in an effort to show the effects of power amplifiers (PA), in the Chireix out-phasing network, on spectrally confined waveforms under certain conditions. Several test results and conclusions are discussed in this paper.
