The Soviet Union produced a number of radars in the second half of twentieth century that provided fire control, early warning and detection. While they were based on Western technology their systems also featured some unique characteristics. Some radars used by the Soviets were not detected by Western intelligence.
The Soviet Union's first radar was a portable, V beam early warning system. The Soviets had extensive experience in radars during World War II. They were familiar with radars built by the United States and knew some details about major British radars. The Soviets eventually decided to create an integrated, radar-based early warning system.
The Soviets also developed a mobile radar, the RUS-2. It was a very simple form of radar that was capable of providing early warning but it had limited range against low-flying aircraft. It consisted primarily of a truck with a trailer. The truck was used to house the radar equipment. The system was also based upon MIT. It had a very basic ECCM feature. However, it was not able to withstand long pulses jamming.
The Soviets also designed a unique height finder. This was the Patty Cake radar and was invented in 1953. It was not built according to the normal development patterns of other Soviet radars. It was not made to replicate Western technology.
The Soviets and the allies also placed a great deal of effort into air defense. The Soviets and allies had large numbers of interceptors aircraft which were used in the destruction enemy aircraft. The air defense system covered Russia in all its entirety, as well Eastern Europe/East Asia. A large number of radar ground control interceptnets were also available to provide continuous coverage throughout the country.
Soviets also created a family of radars to counter the threat posed by stealth aircraft. These systems were built after the NATO invasion of the Federal Republic of Yugoslavia. They were designed on mobile chassis and were tested on training grounds. They were also tested in 2011. The Russian air force was able to continuously detect stealth aircraft with the stealth system.
Russian radars that are the most advanced in Russia today can track and destroy stealth airplanes. The Su-57 is a fifth-generation aircraft that has a radar system that is up to 1,000 times larger than the F-22 and the F-35. These aircraft are designed with large, square intakes that absorb radar waves and make them harder to detect.
The Russian air force has successfully deployed the AGM-88 HARM anti-radar missile. These missiles may be launched by military planes or theoretically by anti-aircraft weapons systems. The missiles can hit targets even if the radar is switched off. HARM missiles were also used by the Ukrainian military. Four missiles were intercepted by the Russian air defense and destroyed by them on September 5. This is believed to be the first successful deployment of an AESA radar in Ukraine.
