Product description

AST-SSPW-30 is a flexible radar signal processor that analyzes various algorithms for each target information (speed, distance, angle) transmitted by the millimeter-wave radar sensor module. Not only the horizontal screening range can be adjusted, the maximum detection range is controllable, and the detection precision and small error are high.

Product function

System features (flexibility):
1. The horizontal "X" direction screening range can be adjusted, and the biasing radar interface end is "+x",
2. The maximum detection range (straight line distance) in the R direction is controllable (maximum 30m,

current system setting 20m),

3. The detection accuracy is +0.01m and the error is 0.2m,

4. Azimuth plane (-6dB), angle 56° (±28 °)
5. Pitch surface (-6dB), angle 37° (±18.5 °).
Abnormal self-test:
1. After entering the blind zone: the analog quantity is 0.3V (constant), and is normal after the blind zone;
2. Phenomenon processing: After power on, the voltage appears to be less than 20mV. The reason is that the
signal line is abnormally connected to the radar;
3. The output is 9.9V when there is no target or the target is greater than 20 meters
