Radar and Weapon

D2N offers two set of products for the Radar and Weapons Systems markets, RF over Fibre and Optical Delay Lines. Our range of RF over Fibre solutions provides a suite of ruggedized products that meet the reliability and durability requirements of customers in the Aerospace, Defence & Homeland Security markets.

With products ranging from 100kHz right up to 40GHz. RF over Fibre modules convert RF signals to optical signals and back. One unit has an optical transmitter which converts the signal from RF to Optical, and a second receiver unit converts the signal from Optical to RF. Both units are connected by the optical fibre of the customer.

RF Optic offers three groups of RFoF modules: low frequency (0.5MHz – 6GHz), high frequency Mini Series (12GHz and up to and including 18GHz) programmable RFoF solutions, and high frequency SFDR MiniQ series (18GHz and up to and including 40GHz) programmable RFoF solutions.

An Optical Delay Line (ODL) system incorporates high-performance lasers such as DFBs, optical modulators for high frequency operation, and photodiodes. It can also incorporate other components such as optical dispersion compensators, optical switches, optical amplifiers and pre- and post RF amplifiers for exceptionally high performance. For various delays, the ODL optical system supports very high bandwidths, high sensitivity with wide dynamic range.

The ODL method is the most accurate and reliable method for time domain measurement for delay times of a few nano seconds to hundreds of microseconds. An Optical Delay Line is a method of wave guide where the media is fibre with a fixed index of refraction and relative constant group delay variation.

There are various applications that can use ODL systems, such as radar range calibration, MTI (moving target indication), clutter canceller, BIT, ground-based system test, radar warning receiver, jammers for EW systems, timing control, path delay simulation, and phase shift discriminator.
