Abstract
The trend in high-performance ground-surveillance radar systems is towards employing multiple receiver channels of data. Often, key to performance is the ability to achieve and maintain balance between the radar channels. This can be quite problematic for high-performance radar modes. It is shown that commutation of radar receiver channels can be employed to facilitate channel balancing. Commutation is the switching, trading, toggling, or multiplexing of the channels between signal paths. Commutation allows modulating the imbalance energy away from the balanced energy in Doppler, where it can be mitigated with filtering.
