Invention:
This technology is a new method for mitigating interference in automotive radar systems. It uses an adaptive noise canceler applied on the frequency-domain data of automotive radar. The method has an ideal performance and can be applied to almost all the existing automotive radars. New method using adaptive filtering only needs signal processing and does not rely on costly hardware improvement. It reduces missing targets and false detections in the radar systems and ultimately improves safety for the driver.
Background:
Currently, almost all of the automotive radar in use today uses frequency modulated continuous wave (FMCW) waveform, and suffers electromagnetic interferences. The interference mitigation technique is a timely technique that can be applied to almost all existing automotive radar to mitigate electromagnetic interferences, which is the bottleneck for widely used automotive radar today. Interference among these radars will be more severe as the number of automotive radars on the road increases significantly.
Applications:
- Adaptive cruise control (ACC)
- Autonomous emergency braking (AEB)
- Blind spot detection (BSD)
- Forward collision warning
- Intelligent park assist
- Advanced driving assistance systems (ADAS)
Advantages:
- Interference mitigation
- Adaptive filter
- Simple
- Low-cost
