Description

Technical Field

[0002] Millimeter-wave radar detects surrounding objects by emitting and receiving millimeter waves. It has the advantages of long measurement distance, high resolution, and a certain resistance to adverse weather conditions. However, millimeter-wave radar has low sensitivity to target features, which may lead to misidentification.

[0003] Cameras provide rich visual information by capturing images. They can observe and identify the features of targets with high resolution. However, cameras have a short viewing range and are easily affected by lighting and weather conditions.

[0005] However, existing millimeter-wave radar-based cameras have smaller millimeter-wave receivers, which results in weaker received millimeter-wave signals. This may lead to limited communication speed, reduced communication stability, limited coverage, weakened anti-interference capabilities, and even image loss.
