Instantaneous frequency measurementMicrowave photonicsFour-wave mixingWe present the first instantaneous frequency measurement (IFM) system using four-wave mixing (FWM) in a compact photonic chip. We exploit the high nonlinearity of chalcogenide to achieve efficient FWM in a short 23mm As2S3 waveguide...
Hi Parth i was following the book you mentioned and the research paper "FPGA-Based 1.2 GHz Bandwidth Digital Instantaneous Frequency Measurement Receiver" by James Helton, Chien-In Henry Chen, David M. Lin and James B. Y. Tsui, DOI 10.1109/ISQED.2008.162. This paper shows 2MHz RMS error a...
An integrated receiver includes an Instantaneous Frequency Measurement (IFM) device, an interferometer and switches. The IFM receives signals from a target and determines the frequency of the signals. The IFM includes the shared N-channel phase receiver. The interferometer also receives the signals ...
Instantaneous Frequency Measurement Receivers (IFM) Wide Band Systems’ Instantaneous Frequency Measurement Receiver Systems (IFM) are fully integrated, Wide Band electronic warfare (EW) system receivers that provide digital output of RF frequency, RF amplitude, RF envelope pulse width, and time of ...
Most radar warning (RW), electronic countermeasures (ECM) and electronic intelligence (ELINT) systems employ instantaneous frequency measurement (IFM) to identify threats, map the electronic battlefield and eventually implement deceptive countermeasures.
Frequency measurement of microwave signal in a wide band range is a very important task in electronic warfare. In this paper, an instantaneous photonic frequency measurement approach based on chromatic dispersion and compressive sensing is proposed. More than two chromatic dispersion related optical power...
