Polyphase radar codes promise enhanced performance and flexibility due to greater design freedom. While the search for better codes continues, the implementation issues of transmitter bandlimiting and nonlinear distortion have precluded their widespread use in high-power systems. This paper introduces a modified continuous phase modulation (CPM)(More)
Maximizing amplifier PAE and associated output power is critical to preserving the detection capabilities of radar systems. The conflicting criterion for maximizing efficiency is amplifier linearity, which is a well studied tradeoff [1,2]. ACPR shows a measure of linearity by directly quantifying the spectral leakage produced at the amplifier output. Load(More)
