Title: The Innovations of Andreas LeFevre
Introduction
Andreas LeFevre is a notable inventor based in Euerdorf, Germany. He has made significant contributions to the field of automotive radar systems, holding two patents that showcase his innovative approach to mitigating interference in radar technology.
Latest Patents
LeFevre's latest patents include a vehicle radar system designed to reduce interference. This system features a transceiver arrangement that generates, transmits, and receives reflected radar signals. The arrangement includes an ADC that outputs a digital IF signal to a DSP arrangement. A key function of the DSP is to identify and retain sample points of the digital IF signal that exceed a certain threshold, forming an approximation signal in the time domain. Additionally, it identifies sections of the digital IF signal that exhibit interference and determines whether to replace these sections with equivalent sections of the approximation signal.
Another significant patent is an apparatus and method for mitigating interference in an automotive radar system. This system employs random inter-pulse jitter in the transmitted radar signal to prevent false track identification due to interference. It also implements random intra-pulse jitter to spread false targets and distinguish them from true targets. Furthermore, adjacent sensors in a multi-sensor radar system are configured to alternate between upward and downward ramping frequencies to mitigate interference.
Career Highlights
LeFevre has worked with prominent companies in the automotive sector, including Veoneer US, Inc. and Veoneer Sweden AB. His experience in these organizations has allowed him to develop and refine his innovative radar technologies.
