Patent number: 10234543Abstract: Embodiments of the present invention concern locating targets using non-linear radar with a matched filter which uses exponential value of the transmit signal. According to embodiments, a method of non-linear radar target location includes: transmitting a signal of a transmit waveform towards a target; receiving a signal from the target; creating a matched filter by generating an exponential function of the transmit waveform corresponding to a particular harmonic of the interest; and applying the matched filter to the received signal to generate and output a signature waveform for the target of the particular harmonic of interest. In other embodiments, the matched filtering may be combined with sidelobe reduction.Type: GrantFiled: April 20, 2016Date of Patent: March 19, 2019Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Gregory J.

Patent number: 10018707Abstract: A novel methodology for automatically linearizing a harmonic radar transmitter—termed Feed-Forward Filter Reflection (FFFR)—is disclosed. The method combines the reflected second harmonic from a filter with the signal passing directly through the filter. The second harmonic from these two paths are combined with equal and opposite amplitudes to reduce the second harmonic beyond filtering alone. This methodology has been experimentally verified at transmit frequencies between 800 and 1000 MHz. Implemented properly, the technique provides greater than 100 dB rejection between 1.6 and 2.0 GHz. Although the tuning has been automated, further optimization is possible. Automated tuning is demonstrated over 400 MHz of bandwidth with a minimum cancellation of 110 dB. One application for the harmonic cancellation is to create a linear radar transmitter for the remote detection of non-linear targets.Type: GrantFiled: May 4, 2015Date of Patent: July 10, 2018Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Gregory J.
