Title: Andrzej Sobski: Innovator in RFID Technology
Introduction
Andrzej Sobski is a notable inventor based in Niles, IL (US). He has made significant contributions to the field of radio frequency identification (RFID) technology. His innovative work has led to the development of a unique patent that enhances the capabilities of LFM radar systems.
Latest Patents
Andrzej Sobski holds a patent for a "Radio tag for LFM radar." This invention involves an RFID system that utilizes encoded digital information through pulsed linear frequency modulation (LFM). The LFM waveform is transmitted from an aircraft or satellite and received by a transponder. The system demodulates the LFM waveform using both AM and FM receivers. The demodulated data is then compared to preprogrammed criteria tables, and after validation, it is decoded and utilized. Algorithms within the transponder determine the frequency deviation and calculate the direction of the slope of the LFM input signal. The valid RF signal is stored in a delay element, encoded with transponder data using phase modulation (PM) and frequency modulation (FM). The tag transmission is synchronized to the input LFM waveform, and the transmit/receive chopping signal prevents unwanted oscillations while allowing for randomization.
