Latest Patents

One of Ohta's latest patents is a target detection system using radar and image processing. This innovative system utilizes EHF radar in conjunction with image processing to reduce processing time. By complementing the weaknesses of both technologies, the system improves reliability. It consists of a radar, an image acquisition unit, and an image processing ECU. The microcomputer within the ECU identifies an image recognition area based on radar power output, allowing for image processing to occur only in the specified area. This targeted approach not only shortens processing time but also minimizes erroneous detections, such as letters on road surfaces.

Another significant patent is the method and device for distance measurement by pulse radar. This invention aims to eliminate false echoes from distances beyond the detectable limit set by the pulse generation cycle. The pulse radar includes a pulse signal sending unit that generates pulse signals with varying cycles, which are sent to targets at predetermined intervals. The reflected signal receiving unit captures these signals and stores the data in RAM. The reflected signal identification unit then compares the intensity of reflected signals obtained at the same lag time point, ensuring accurate identification of the reflected signals.
