Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in efficiently managing multiple antennas on a single platform, such as vehicles or aircraft, which are aesthetically unappealing, cause interference, and require expensive wiring, while also being limited by space and functional constraints, especially in military applications where specialized solutions can be costly and risky.
Innovation Solution
A method is introduced to utilize a radar system for both transmitting and receiving data by dividing a communication signal into symbol sections, which are transmitted during radar burst intervals, allowing for a two-way data link and reducing the need for additional antennas and hardware.

1Adaptability or versatility
If multiple antennas are installed on a single platform to provide diverse communication capabilities, then communication versatility is improved, but device complexity and interference increase
Solution Approach 1:
The patent applies multi-functionality by enabling the radar system to perform both radar detection and data communication functions. The radar transceiver is configured to transmit and receive data signals during radar burst intervals, eliminating the need for separate dedicated communication antennas and reducing overall system complexity while maintaining communication versatility.
Solution Approach 2:
The patent merges the radar and communication functions into a single integrated system. By combining the radar transceiver with data communication capabilities, the system transmits and receives both radar pulses and data signals through the same antenna structure, thereby reducing the total number of antennas and wiring requirements.

AI summary
A method for transmitting low data rate symbols from a burst radar transceiver is disclosed. The method includes dividing a symbol having a symbol period into a plurality of symbol sections. Each symbol section has a symbol section interval that is less than or equal to a burst interval of the radar transceiver. At least two symbol sections can be transmitted with the burst radar transceiver. Symbol energy can be accumulated from the at least two symbol sections at the communications terminal. Information in the received symbol sections can be identified based on characteristics of the accumulated symbol energy.
