“…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) .…”

“…Based on TDM, the spectrum of a microwave signal to be measured is mapped into the temporal domain by using an optical wavelength scanning source (WSS) or a frequency shifting recirculating loop , to generate multiple temporally separated time slots in series. By analyzing the time slots of the obtained temporal waveform, a TDM‐based microwave channelizer can be realized at a high resolution.…”

“…Other solutions based on TDM can be implemented using coherent detection or Nyquist‐bandwidth detection . To extend the frequency measurement range, in a frequency‐to‐time mapping approach based on successively frequency shifting the modulation sideband of an optical signal was proposed to perform TDM‐based spectrum measurements. A readily extended frequency measurement range to 100 GHz can be achieved for the channelizer, while retaining a channel resolution of 250 MHz.…”

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.

“…Photonic frequency scanning approaches, on the other hand, form the third class for implementing microwave frequency measurement [12][13][14][15][16][17][18][19][20]. This technique can be realized in a simple configuration with a single laser, an electro-optic modulator (EOM), an optical filter, and a low-speed photodetector whilst demonstrating the capability to perform single and multiple frequency measurements.…”

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.

“…One application to which recently much attention is attracted is MWP assisted electronic warfare (EW) systems [11][12][13]. Some instances are instantaneous frequency measurement receivers [12][13][14][15][16][17][18][19], scanning receivers [20,21], channelized receivers [22][23][24], and reconfigurable beam-forming systems [25][26][27][28].…”

A standalone microwave photonics system for Doppler frequency measurement purposes is conceived and demonstrated practically. The system exhibits a maximum of 1.61% relative error in Doppler frequency estimation at the worst case. Utilization of all optical mixing has enabled RF frequency independent operation. The system is thus capable of operating at any radar carrier frequency up to 40 GHz. This makes it a perfect candidate for various types of photonic-based radars and frequency agility systems.Index Terms-Frequency estimation, frequency measurement, Doppler radar, Doppler measurement. 0733-8724 (c)
