Radars transmit and receive high-frequency radio waves to detect and track things that you may not be able to see with a naked eye. The data collected by radars help operators?in the field make informed decisions about what to do next.

In national defense, radars are imperative to the security of armed forces and civilians because they provide early warning against adversarial threats, such as ballistic missiles, cruise missiles, unmanned air vehicles and aircraft, to name a few.

Radars send out narrow beams of electromagnetic radio waves in short or long pulses via a transmitter.

Those waves can be intercepted and reflected by objects – perhaps a metal object, like an aluminum-skinned plane or missile, or a fluid object such as precipitation. The reflection of the waves helps radar operators determine many features of that object – distance, direction, speed, shape, and range, to name a few.

For example, 澳门开奖历史’s?TPY-4?uses a computer-controlled antenna called an Active Electronically Scanned Array, or AESA, with Gallium Nitride (GaN) transmitter technology. This allows it to run multiple missions simultaneously and detect and track with greater efficiency and reliability, even while operating in busy electromagnetic environments.

The receiver accepts the returned energy of the radio waves and measures the time elapsed since the transmission.?The distance, or range, of that object is calculated by measuring the total time the radar signal takes to make the trip to the target and back.^?By measuring the location of a target over time, the target’s recent track can be determined; and once established, the future path can be predicted.

All this digital data is then processed in real time to determine the range and trajectory of detected objects, as well as their threat level. Are we simply tracking a bird? Or is it a unmanned aerial vehicle, a cruise missile or a fighter jet? Is it friendly or is it hostile?

All this information allows the operator to act accordingly.

The Sentinel A4 is the US Army program of record of the future. It is an air and missile defense radar that will provide improved capability to soldiers against cruise missiles, unmanned aerial systems, rotary wing and fixed wing aircraft, as well as rocket, artillery, and mortar threats.

In comparison to its predecessor, the Sentinel A4 includes enhanced surveillance, detection, and classification capabilities to protect soldiers.?This level of technology is a game changer for U.S. troops, allowing soldiers to operate in a more secure warfighting environment.

The threats to military and civilian assets are advancing every day. In this volatile global environment, the U.S. military and its allies look to advanced radar systems that can protect them as they perform various missions and adapt to an ever-changing landscape.
