The role of BP905 bandpass filter in MEMS radar scanning
Improve signal quality
MEMS radar usually relies on near-infrared bands (such as 905nm) for signal transmission and reception. By allowing only 905nm light to pass, the BP905 filter can significantly reduce interference from other wavelengths, allowing the radar receiver to obtain a purer signal, thereby improving the accuracy of radar imaging and ranging.
Reduce environmental interference.
In outdoor or complex light source environments, background light may affect the signal of MEMS radar. The BP905 filter isolates out-of-band light to reduce the impact of natural light, car lights or other irrelevant light sources to ensure stable operation of the system.
Improve target detection accuracy
For radar systems, it is crucial to identify the outline and features of target objects. Using the BP905 filter can help the system focus on the echo in the 905nm band, thereby accurately identifying and analyzing the distance, shape and movement speed of the target object, and improving the accuracy of the MEMS radar.
Support LiDAR system.
The LiDAR module in MEMS radar widely uses 905nm light source for ranging and scanning. The BP905 filter has a high transmittance at this wavelength, which ensures that the LiDAR module effectively receives the reflected signal while reducing system power consumption and energy waste. It is an important component in the field of unmanned driving and autonomous driving.
Improve system reliability
The BP905 filter has heat resistance and shock resistance, and is suitable for use in high-speed and complex environments, ensuring the stability and reliability of the long-term operation of the MEMS radar system.
