OREANDA-NEWS. Fujitsu Limited and Fujitsu Laboratories Ltd. announced that they have developed an interference-simulation technology for millimeter-wave radar, which is used in automotive radar and other applications.

The 76-GHz millimeter-wave band has come into widespread use for things like motor vehicle radar, although the 79-GHz band is also expected to become popular for its higher resolution. But as radar systems become more widespread and more modulation types are used, there is a growing need to study in detail whether or not interference occurs. Because millimeter-wave radar uses a wide bandwidth, it has been difficult to perform analyses of interference from different modulation types with general purpose PCs using conventional approaches because of their limitations in processing performance. Now Fujitsu and Fujitsu Laboratories, by creating a mathematical model of these different modulation types that simplifies analysis without sacrificing precision, have developed simulation technology that can analyze interference on a typical PC with ordinary memory and performance levels.

This technology can be used in simulations when developing and testing interference-avoidance algorithms as a way of preventing object-recognition oversights and mistaken detections and developing more reliable automotive radar systems. This research was conducted through R&D to "Advanced Research on 79GHz-band Radar Systems", commissioned by Japan's Ministry of Internal Affairs and Communications for its "Research and Development for Expansion of Radio Wave Resources" program.
