This advanced RFI signal detection technology relies on instantaneous frequency measurement (IFM) receiver systems originally developed for electronic warfare applications in the defense market.
Most applications involve instantaneous frequency measurement, such as in military electronic systems for frequency identification.
Instantaneous frequency measurement (IFM) receivers provide a digital frequency measurement in an extremely short time but with limited sensitivity.
When wider instantaneous coverage is required, a true multi-correlator instantaneous frequency measurement (IFM) is required.
Instantaneous frequency measurement (IFM) receivers operate by splitting the incoming signal into two or more paths of differing lengths so as to generate phase differences proportional to frequency.
The multicorrelator delay line instantaneous frequency measurement (IFM) receiver has become the cornerstone of ESM, ELINT and radar warning receivers (RWRs), where high probability of intercept is required.
The model NSL-1058 wideband instantaneous frequency measurement IFM receiver operates over a wide variety of instantaneous bandwidths, including 2 to 4 GHz, 2 to 6 GHz and 6 to 18 GHz, and provides instantaneous digital frequency, amplitude, pulse width and time of arrival.
There are a number of receivers, such as the superheterodyne receiver (SHR), instantaneous frequency measurement (IFM), and crystal video receiver (CVR), that have been the mainstay of EW systems.
In general, crystal video and instantaneous frequency measurement (IFM) receivers are used for low- to medium-cost systems operating in high-density pulse signal environments.
An instantaneous frequency measurement (IFM) receiver can measure frequency accurately even on a short pulsed signal.
In all cases, channelized receivers are more complex than single superheterodyne receivers, instantaneous frequency measurement receivers or crystal video receivers.
Crystal video and instantaneous frequency measurement (IFM) are examples of direct detection.
