\nSystem composition<\/strong><\/p>\n

\"\"<\/p>\n

System block diagram is as shown above. The data fusion module utilizes SPI interface to read forward and backward detection radar SP25T and the altimeter NRA24 and realizes the data fusion, and then through the UART, CAN interface to transmit the data to the UAV flight control system. Also users can directly connect SP25T and NRA24 radar for data collection and integration.<\/p>\n

\"\"<\/p>\n

“1 + 2” solution adopts 1 NRA24 mmw radar sensor and 2 SP25T mmw radar sensors . Based on this solution, UAV customers can quickly build their own flight platform, and design different UAV-aware system suitable for their application scenarios.

\nInstallation<\/strong>
\nMillimeter wave terrain awareness radar in UAVs adopts standard modular for the distributed installation, which is easy to assemble around the body of the UAV. The installation diagram is as shown below.<\/p>\n
