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 arrival (TOA) data. Many different configurations are available for frequency coverage from 0.5 GHz to 18 GHz.

Wide Band IFMs are also available with many other discrete performance options including:

  • Frequency Modulation on Pulse (FMOP)
  • Phase Modulation on Pulse (PMOP)
  • Time of arrival (TOA)
  • Angle of arrival (AOA)
  • CW detection
  • Customer defined specifications

Typical applications include:

  • Radar Warning Receivers (RWR)
  • Electronic Intelligence Systems (ELINT)
  • Signal Intelligence Systems (SIGINT)
  •  IFM Receiver 0.5 - 18.0GHz
