  • Patent number: 10320499
    Abstract: In some applications network parameters vary over time in a manner that precludes the use of conventional swept frequency network analyzers. Swept measurements incur penalty both in terms of acquisition time, and in terms of registration between measurements taken at the beginning and at the end of a sweep. Disclosed is an architecture and method for real-time analysis of network parameters. Example applications are presented, ranging from thermal drift of amplifiers, to microwave imaging of moving objects, to characterizing materials on conveyors, to characterizing plasma buildup, and many more.

  • Patent number: 9094241
    Abstract: Disclosed is an improved channel estimation by post-processing of the channel response that is generated by a Golay correlator The processing is done using time-domain operations such as gating and filtering. Gating is performed on the estimated channel response taps in order to reduce the noise level. Pre-filtering the channel response through a filter matched to the transmitted pulse-shape improves the probability of detecting the channel peaks. Post-filtering the processed channel impulse response to eliminate the high frequency effects that are added by the windowing and gating operations.

  • Publication number: 20140276031
    Abstract: A microwave imaging sensor is disclosed which is resilient to background and skin clutter. Resilience is obtained by cancellation of skin reflections without mechanical displacement of the microwave antenna array or the subject, by utilizing reflections from other antennas and compensating for differences in propagation. The cancellation takes into consideration the expected strength of the reflection at different points in time and for different pairs, in order to minimize the effects on the image, and particularly on image reconstruction of symmetric targets.

  • Patent number: 8675720
    Abstract: A noise estimation filter for an orthogonal frequency-division multiplexed (OFDM) system can include a filter bank module, a coefficient squaring module, and a summing module. The filter bank module can multiply a unitary vector by an OFDM signal vector to generate scalar products of the OFDM signal vector. The coefficient squaring module can square the scalar products and weight the scalar products to generate a plurality of weighted single estimates. The coefficient squaring module can include a squaring module for squaring the scalar product to generate a plurality of single estimates and a coefficient multiplication module for weighting each of the single estimates with a noise coefficient forming a plurality of weighted single estimates. The summing module can sum the weighted single estimates to generate a noise and interference power estimate.
