Methods and systems for implementing and using dual-mode radar and communications devices

A system comprising:

• a dual-mode module configured to support a plurality of operation modes comprising at least a radar mode and a data communications mode, the dual-mode module comprising:
• one or more antennas comprising at least a first phased array antenna and a second phased array antenna;
• one or more processing circuits configured for handling communication via the one or more antennas, wherein the one or more processing circuits are shared between at least the radar mode and the data communications mode;
• one or more frequency generation circuits shared between at least the radar mode and the data communications mode;
• one or more power management circuits shared between at least the radar mode and the data communications mode;
• and
• one or more switching circuits configured for facilitating switching between at least the radar mode and the data communications mode;
• wherein one of the first phased array antenna and the second phased array antenna is configurable for radar transmission and other one of the first phased array antenna and the second phased array antenna is configurable for radar reception;
• wherein at least one of the first phased array antenna and the second phased array antenna is configurable for use in the data communications mode;
• and
• wherein the dual-mode module switches between operation as a radar module and operation as a communications module.
