Understanding the Subsystem that allows for Electronic Warfare


The world has seen an unimaginable evolution over the last few years, in the development of superior weapons and tactics. The term electronic warfare is not new to many people, especially those who have an interest in military combat as well as those who follow the current world conflicts in the news.


The term electronic warfare has been embraced as part of military technology for quite some time now. In fact, communication jamming occurred during the first world war.


Most current military operations are done within what is called an information environment where electronic warfare is a part of that information warfare that is electronic warfare is part of the offensive and defensive strategy of counter-information. Today, the dependency of military operations on Electronic Magnetic Surveillance (EMS) is a central facet of almost all military activities as military forces around the world have integrated EM capabilities into a vast majority of platforms, systems, and components.  Let’s take a closer look.



Defining Electronic Warfare


Electronic warfare (EW) is essentially any type of action where the use of the electromagnetic spectrum (EM spectrum) is involved to either attack the enemy or interfere with the enemies’ assaults.


In such a high-risk environment, the goal of electronic warfare is to gain uninterrupted access to the electromagnetic spectrum and protect its users while at the same time making sure that the opponent’s EM use is interfered with. Electronic warfare is generally divided into three types based on their application:


  • Electronic support. This is used to receive and analyze the transmissions of the opponent including the location of radar signals or the identification of communication signals. A good example of this is the radar warning receiver (RWR), which is usually installed in cars to notify the driver of an impending speeding ticket if he doesn’t slow down.
  • Electronic attack. The electronic attack is the most commonly used application in electronic warfare, this method uses a set of technologies to attack equipment, facilities, and even personnel to interfere with or completely destroy the opponent’s use of the electromagnetic spectrum.
  • Electronic protection. On the contrary, electronic protection is the method of using technologies to protect against an electronic attack. For instance, when an electronic attack targets to jam a radar signal, electronic protection technology is used to resist it.



Understanding the RF and Microwave Components of Electronic Warfare  


With electronic warfare increasingly becoming more competitive, several RF and microwave components have been developed over the years, both to either enhance the ability for the electronic attack on an enemy or to assure more protection from electronic attack from an outside source.  Some of the most important subcomponent systems are:

  • Wideband Intelligent RF Spectrum Exploits and Monitoring (WISDEM) offers real-time monitoring and characterization of the RF spectrum for a higher probability of detecting the opponent’s signals.
  • High Powered Tunable Agile RF Filters removes harmful interference from Signal Intelligence (SIGINT) frequencies or communication data during an electronic attack. These filters offer more than 100dB of in-band attenuation and their efficiency has been validated in both the US Army and US Navy electronic warfare labs.
  • Predistortion-Based Amplifier Linearization Module (PALM) removes harmful interference from communication Data or SIGINT frequencies. It is a signal-agnostic linearization module that’s attached to an RF high power amplifier that’s operable in UHF, VHF, HF, and even low microwave spectrums.
  • Shipboard Electronic Warfare Suite (SEWIP) protects the electromagnetic spectrum from any interference during an attack by removing RF power in selected bands.
