In the first post of this series, we discussed the history of electronic warfare as it was being developed during WWII. While much has changed in the last 80 years, one constant remains true—the cat-and-mouse game to develop the superior technology that grants the owner control over the electromagnetic spectrum (EMS). When one nation deploys a new radar system, its adversary begins work on the technology to jam the radar. This prompts the first nation to modify their radar system with new features to protect it from the jammer, which brings us to the final topic in this series—electronic protection.
In the first post of this series, we discussed the history of electronic warfare with an emphasis on the back-and-forth competition to develop systems that grant the owner control over the electromagnetic spectrum. When one country develops a new radar system, its adversary starts working on a jammer. In order to mitigate the effects of the jammer, the radar developer then must design a system that protects the radar from those effects.
This invisible battle over control of the electromagnetic spectrum is critical to success on the battlefield and is the topic of the subsequent posts. However, understanding the technology to jam and deceive radar requires an understanding of the radar systems.
We’re all familiar with the applications of radar—that yellow warning light on your mirror telling you someone is in your blind spot, police radar monitoring your speed, images on the news showing the path of a storm. However, for the purpose of understanding electronic warfare, we’ll look at the types of radar in three main groups.
