Miniature nonlinear transmission line (NLTL)-based frequency-scalable ultra-wideband spectrum analyzer
10837998 · 2020-11-17 · ·

A spectrum analyzer for measuring an electrical response of a device under test (DUT) includes a test port for receiving radio frequency (RF) signals from the DUT in response to a test signal transmitted to the DUT, a local oscillator (LO) for generating a LO signal, a sampler connected with the LO to receive the LO signal and a receiver connected with the sampler. The sampler includes a non-linear transmission line that generates a sampler signal having a frequency that is a multiple of a frequency of the LO signal, and an input for receiving a RF signal from the test port. When a RF signal from an RF input source is received the sampler outputs an intermediate frequency (IF) signal. The receiver receives the IF signal output of the sampler.

HIGH RESOLUTION SPECTRUM MONITORING

A method, a system, and a computer program for executing high resolution spectrum monitoring. A sensor receives an input signal having a varying frequency content over time. One or more samples of the received input signal are sampled. The samples of the received input signal include one or more swept signal samples generated by sweeping, using a center frequency of the sensor, the received input signal across an entire frequency spectrum associated with the received input signal. Sampling of the samples of the received signal is performed while performing the sweeping. The signal samples are processed.

Sub-noise detection of a fast random event
10788520 · 2020-09-29 ·

Observation of random, non-repetitive phenomena is of critical importance in astronomy, spectroscopy, biology and remote sensing. Heralded by weak signals, hidden in noise, they pose basic detection challenges. In contrast to repetitive waveforms, a single-instance signal cannot be separated from noise by averaging. The present invention demonstrates that a fast, randomly occurring event can be detected and extracted from a noisy background without conventional averaging. An isolated 80-ps pulse was received with confidence level exceeding 99%, even when accompanied by noise. The detector employed in the present invention relies on instantaneous spectral cloning and a single-step, coherent field processor. The ability to extract fast, sub-noise events is expected to increase detection sensitivity in multiple disciplines. Additionally, the new spectral-cloning receiver can potentially intercept communication signals that are presently considered secure.
