The Ukrainian Armed Forces use American radars to destroy Russian equipment in the Donbas (video)

Must read

The Sentinel radar system has a short range, but effectively assists air defense to destroy incoming threats such as missiles and UAVs.

Ukrainian soldiers began to actively use the AN / MPQ-64 Sentinel radar to counter the Russian troops in the Donbass. This was reported by the Defense Blog citing a video shot and posted by the military. excitement OSINT analyst.

In April, the US sent Ukraine a new military aid package containing two AN/MPQ-64 Sentinel radars. According to the description of a similar video on YouTube, one of them was deployed in the Donbas in June.

Sentinel is a short-range 3D radar used to detect threats and quickly alert air defense forces. The radar system operates in the X band of radio frequencies (8 – 12 GHz) and uses the Doppler effect – a change in frequency and wavelength as it moves relative to the source device. The maximum range is 75 km, but effective operation is limited to 40 km.

The antenna provides phase frequency electronic scanning, which creates a three-dimensional picture for comprehensive observation. It is mounted on a fast rotating platform (30 rpm) for fast 360 degree scanning. The towed platform allows the antenna to be away from the base unit and operate autonomously, communicating with the fire control center via a broadband fiber optic line or SINCGARS, a single-channel military-style ground radio system used by the US Army.

The developers provided the radar with high resistance to electronic warfare and anti-radar missiles. Sentinel interfaces with various air and missile defense architectures, particularly the Increase I Missile, Artillery, Mortar (C-RAM) system, to protect friendly aircraft when firing at difficult targets.

American radar can be modified to improve its ability to detect, identify and classify targets, including unmanned aerial vehicles and cruise missiles. In addition, it is planned to upgrade the processor that processes the signals, as well as introduce an active phased antenna array (Active Electronic Scanned Array) – the essence of the technology lies in the propagation of radio signals by many independent elements. It allows you to direct the beams in different directions without changing the position of the antenna.

In May, Pentagon spokesman John Kirby said 15 UAF fighters had been trained to use AN/MPQ-64 Sentinel radars. In addition, 220 soldiers were trained and learned how to use the American M777 howitzer.

Earlier, the military demonstrated “smart” radars that can detect stealth aircraft and hypersonic missiles. US company Northrop Grumman has developed the AN/TPY-5(V)1 long-range system, which has been extensively tested and approved by the US government.
