The Single Channel Ground and Airborne Radio System (SINCGARS) is a family of Very High Frequency (VHF), Frequency Modulated
(FM) radio sets.
Suitable for use in hazardous areas, the BM 702 level gauge is reputed to be the first 2-wire Frequency Modulated
Continuous Wave (FMCW) radar level device.
The frequency modulated
pulse is transmitted and received just like a fixed-frequency pulse, but in the receiver, it passes through a compressive filter.
This acoustic frequency modulated
signal has a center frequency of 90 kHz and a 20 kHz bandwidth.
AMPS transmits an unencrypted analog frequency modulated
(FM) signal, which can be intercepted with any FM receiver, such as a scanner.
Blighter radars combine patented solid-state Passive Electronic Scanning Array (PESA) technology with advanced Frequency Modulated
Continuous Wave (FMCW) and Doppler processing to provide a robust and persistent surveillance capability and an unmatched combination of high reliability, accuracy and performance with a low cost of ownership.
The Centerwave 6000 is said to be key technology for quality assurance during the extrusion of big tubes, and features several transceivers arranged around the circumference of a tube, sending and receiving continuous frequency modulated
millimeter waves for a non-contact and [micro]m-precise online measurement of diameter, ovality and wall thickness for larger tubes during the extrusion.
