However,  utilizes the DRFM
structure to perform the periodic modulation, which will induce the jammer hardware structure to be somewhat complex.
CRISIL believes that DRFM
will sustain its working capital management and, consequently, will retain its gearing at the current levels.
A block diagram of the LNX DRFM
ASIC is shown in Figure 2.
DFD products rapidly measure the frequency of a radar signal for identification and classification; while DRFM
products digitally store and regenerate radar signals with excellent fidelity to deceive radar systems
Caption: Selex ES is finalising the development of the expandable DRFM
(Digital Radio Frequency Memory) decoy which is to be available on the market around mid-2014.
Additionally, the company is a leading supplier of defense subsystem products including Digital Frequency Discriminators (DFDs), Digital Radio Frequency Discriminators (DRFMs
), and other custom-designed microwave subsystems: DFD products rapidly measure the frequency of a radar signal for identification and classification; while DRFM

has the capability to delay the captured signal.
are a critical component in complex and sophisticated RF simulation systems utilized to test a broad line of active radar sensors and systems, and the takeover will fortify VadaTech's solution offering in radar systems.
The decoys performed as planned, automatically detecting threat radars and jamming them with the decoy's embedded DRFM
solutions have been used for over two decades for training and radar environment simulation, vulnerability assessment and self-protection.
This time around, the AN/ALQ-187 jammer will include a digital RF memory (DRFM
), and the jammers supplied for the first batch will be backfitted with DRFMs
The multi-frequency jammer systems based on DRFM
= Digital Radio Frequency Memory) simulate electronic jamming attacks, with the help of which, for example, processes can be developed to protect aircraft from radar-guided missile attacks.
