“…A microwave channelizer is a device that is able to slice the spectrum of a microwave signal into a bank of narrow channels and each channel provides a high‐resolution and high‐sensitivity measurement for a channel bandwidth in this channel. Currently, photonic‐assisted microwave channelizers have been developed based on space‐division multiplexing (SDM) , wavelength‐division multiplexing (WDM) , and time‐division multiplexing (TDM) .…”

“…Microwave channelization with a channel resolution of X GHz is thus realized. The same approach was also implemented by replacing the sliced incoherent light source with an OFC, to improve the signal quality at the output of the demultiplexer and the tuning operation of the system . For the channelizers reported in , the channel resolution was mostly estimated to be ±2.5 GHz or ±0.5 GHz, which was limited by the bandwidth of the used optical etalons or filters.…”

As an emerging topic, photonic-assisted microwave measurements with distinct features such as wide frequency coverage, large instantaneous bandwidth, low frequencydependent loss, and immunity to electromagnetic interference, have been extensively studied recently. In this article, we provide a comprehensive overview of the latest advances in photonic microwave measurements, including microwave spectrum analysis, instantaneous frequency measurement, microwave channelization, Doppler frequency-shift measurement, angle-of-arrival detection, time-frequency analysis, compressive sensing, and phase-noise measurement. A photonic microwave radar, as a functional measurement system, is also reviewed. The performance of the photonic measurement solutions is evaluated and compared with the electronic solutions. Future prospects using photonic integrated circuits and software-defined architectures to further improve the measurement performance are also discussed.

“…The first class is formed by channelized receivers, which perform frequency measurement by splitting and filtering the input radio frequency (RF) spectrum into multiple narrowband channels to monitor and detect the presence of any incoming RF signals in each channel. Technologies such as optical combs, parametric mixers, spectral hole burning, and temporal channelization [2][3][4][5], have been demonstrated to realize a channelized RF filter bank. These schemes require multiple light sources or a bank of highly selective optical filters in combination with an array of photodetectors, both of which incur significant bulk and weight.…”

We present a novel technique based on matrix pencil assisted deconvolution to improve the measurement resolution in scanning receiver systems for microwave frequency measurements. By modeling the scanning receiver output as the cross-correlation of the input modulated signal with the filter's spectral response and applying the matrix pencil algorithm to convolve the detected optical signal at the receiver output, our technique offers precise estimations of both the frequency and power information of microwave signals with an improved measurement resolution. A multi-tone microwave signal measurement based on an optical filter is experimentally demonstrated, showing a significant measurement resolution reduction from 1 GHz to 0.4 GHz for two radio frequency (RF) tones, which is only about 30.2% of the optical filter bandwidth.

“…The RF signal replication facilitates parallelization of signal processing that overcomes the bandwidth limitations set by a single backend digital receiver, therefore enabling a staring wideband RF monitoring. Two approaches have been investigated to generate RF signal replicas: one is based on parametric multicasting, where signal is copied as part of parametric optical comb generation [2,3] and the other one where an optical frequency comb was modulated by the signal to produce the multiple signal copies [4,5]. In this paper, we report on two designs.…”

RF photonic channelizers can overcome limitations of conventional electronic methods for analysis of wideband RF spectral content. Here, we will present a recent progress on the RF photonic channelizer systems that are based on optical parametric combs. These systems can analyze very wide RF bandwidths exceeding 100GHz, therefore providing essential capability for the applications demanding a wide-bandwidth spectral analysis. The RF channelizers being presented utilize parametric processes in the highly non-linear fiber mixers to generate a large number of RF signal copies in the optical domain. Two different implementations for generation of RF signal copies will be presented and compared: one using a parametric multicasting and another utilizing a direct comb modulation. Generation of optical combs spanning more than 10THz will be shown. We will also present two distinct system architectures for RF photonic channelizer system: one employing a periodic optical filter such as Fabry-Perot etalon to select channels from the signal comb, and another one utilizing a coherent detection between a frequency-locked signal comb and a parametrically generated local oscillator (LO) comb. The second scheme gives benefit of providing both in-phase and quadrature (I/Q) information on channelized intermediate frequency (IF) signals. We will present a system with 32 implemented channels using a filtered scheme and a 32-channel coherent system with a full-field detection implemented on one tunable channel. Sensitivity and dynamic range as well as benefits of both system architectures will be discussed.
