What is the primary function of the Janus array in Doppler navigation systems?

In Doppler navigation systems, the primary function of the Janus array is to track multiple targets simultaneously. This capability is crucial in environments where multiple objects or entities are moving, as it allows the system to differentiate between these targets and monitor their movements accurately. The Janus array utilizes advanced signal processing techniques to manage and process the returns from various targets, ensuring that the radar can effectively distinguish between them. This multi-target tracking is essential for applications in air traffic control, maritime navigation, and military operations, where understanding the dynamics of several moving targets is critical for safety and operational effectiveness.
