Abstract:
A radar pulse generator includes a multiplexer, a polyphase synthesizer, a first signal channel and a second signal channel. The multiplexer has a baseband radar pulse input, a multiplexer control input, a first channel output and a second channel output. The baseband radar pulse input signal is a single channel baseband radar pulse signal. The multiplexer control input signal selects one of the group consisting of the first channel output and the second channel output. The polyphase synthesizer synthesizes the first channel output signal, synthesizes the second channel output signal and outputs a desired radar pulse signal based on the synthesized first channel output signal and the synthesized second channel output signal. The first signal channel provides the first channel output signal from the first channel output to the polyphase synthesizer. The second signal channel provides the second channel output signal from the second channel output to the polyphase synthesizer.
