Latest Patents

One of Gorham's latest patents is the "Radio tag for LFM radar." This invention features an RFID system that utilizes encoded digital information with pulsed linear frequency modulation (LFM). The LFM waveform is transmitted from an aircraft or satellite and received by a transponder. The waveform is demodulated using both amplitude modulation (AM) and frequency modulation (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 a transmit/receive chopping signal prevents unwanted oscillations while allowing for randomization.

Another significant patent is the "Detector system for identifying the frequency of a received signal useful in a channelized receiver." This method and apparatus determine the frequency of an RF signal by sequentially applying the received RF signal to selected individual filters with predetermined frequency pass bands. The system compares the magnitudes of the filtered and unfiltered RF signals to determine the frequency of the RF signal based on the filter that outputs the largest magnitude signal. Signals that do not meet the required magnitude are not processed by the system.
