Abstract
Methods and radio frequency (RF) Doppler emulator circuits for emulating Doppler spread in an RF domain. The RF Doppler emulator circuit includes a power splitter, a signature control circuit, a first variable attenuator, a second variable attenuator, and a power combiner. The power splitter is configured to receive an RF input signal and generate a first signal and a second signal using the RF input signal. The signature control circuit is configured to generate a third signal using the first signal. The signature control circuit is further configured to generate a fourth signal using the second signal. The first variable attenuator is configured to generate a fifth signal using the third signal. The second variable attenuator is configured to generate a sixth signal using the fourth signal. The power combiner is configured to generate an RF output signal by combining the fifth signal and the sixth signal.
