4) Start to test. NRA15 radar antenna faces directly to the moving target, or there is relatively
small movement between the sensor and the target. You can see the target indicator of the red
triangle in the UI interface, and the target distance R. In Figure 5, the radial distance of the
target from the radar is 6.03 meters (NRA15 could detect the target within 100 meters to
ground). If no red triangle is indicated, it states that there is no target within the detectable
distance and field of view.
5 Serial-port data parsing
NRA15 radar sensor utilizes a UART-TTL interface with a default transmission rate of 115200
baud. Starting with a start sequence and terminating with a termination sequence for each data
message. At each data cycle of NRA15 (20ms), the message for NRA15 system status and
target output status would be output. If the field of detected target numbers in message of the
detected target output status is 1, the target output status message is followed by the target
output information message which contains the height parameter of the target.
PC or the peripheral device configures the NRA15 with the same message format, and the
corresponding message ID is 0x200.
A complete data message of UART-TTL communication is 14 bytes. Each byte of data is
