Phased Array on Counter UAV Radar — Low-Altitude Surveillance Radar

Radar Basics: Mechanical Scan, Phased Array, AESA, and Over-the-Horizon Detection

Radar is often described as if it were mysterious or only military. Its core logic is much simpler: send electromagnetic energy into a region, receive the reflected echo, and process the return into information about distance, direction, speed, or movement. What makes radar technically rich is not the basic loop itself. It is the many ways engineers have improved beam control, timing, measurement, and coverage behavior around that loop.

For beginners, the most important distinction is not between one brand and another. It is between the major ways radar systems steer attention and solve geometry.

TAS vs TWS in Radar: Update Rate, Search Coverage, and Target Capacity Explained

Thu, 26 Mar 2026 00:00:00 +0000

TAS and TWS often appear as short capacity labels on radar product pages, but they do not describe the same job. TWS normally means Track-While-Scan: the radar keeps searching its assigned volume while maintaining track files on detected objects. TAS is less universally standardized, but in multifunction-radar literature it commonly means Track-And-Scan or Track-And-Search: the radar inserts more dedicated tracking attention for selected targets instead of treating every object only at the baseline surveillance revisit.

What is Radar? (Complete Guide)

What is radar? Radar is a system that sends out radio waves and listens for the echoes that bounce back. From that returning signal, it can estimate where something is, how far away it is, whether it is moving, and sometimes what kind of object it may be.

The word radar comes from Radio Detection and Ranging, but modern radar does much more than simple detection. It can track aircraft, map rainfall, watch sea traffic, help cars avoid collisions, and build images of the Earth from space. This guide explains the idea in plain language so a beginner can understand the basics without getting lost in textbook detail.

What is AESA Radar?

What is AESA radar? AESA radar is a radar that uses an active electronically scanned array to steer its beam very quickly without depending only on a mechanically rotating antenna.

That sounds technical, but the beginner version is simple. Instead of having one big transmitter feeding one moving antenna, an AESA radar uses many small transmit/receive elements across the face of the array. By changing the timing and phase of those elements, the radar can point energy in different directions electronically.
