Fujitsu Ltd. and Fujitsu Laboratories Ltd. today announced the development of a new interference-simulation technology for millimeter-wave radar as part of a project commissioned by Japan’s Ministry of Internal Affairs and Communications.
According to the company, as radar systems operating in the 76-GHz millimeter-waveband become more widespread and more modulation types are used, there is a growing need to study in detail whether or not interference occurs. However, “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.”
The new simulation technology, however, is capable of analyzing interference on a general purpose PC with ordinary memory and performance levels by using a mathematical model of these different modulation types that simplifies analysis without sacrificing precision, the company says. The technology is ideal for testing interference-avoidance simulations to assist with the development of more reliable automotive radar systems and prevent object-recognition oversights and mistaken detections.
Practical testing of a recently developed interference-avoidance algorithm is expected to be completed by the end of 2013. Products incorporating the interference-avoidance algorithm will follow.
