Target Tracking on Counter UAV Radar — Low-Altitude Surveillance Radar

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 Target Tracking (TWS)?

What is target tracking in radar? Target tracking means maintaining a continuing estimate of where a target is, how it is moving, and where it is likely to be next.

That is different from simple detection. A detection says, “something was seen here.” A track says, “this is the same object over time, and the system is following it.”

When people say TWS, they usually mean track-while-scan. That is a radar operating idea in which the system keeps searching the wider scene while also updating known tracks.

Drone Detection vs Drone Tracking: Understanding the Difference and System Requirements.

Drone detection and drone tracking are related, but they are not the same task. Understanding the difference matters because the system requirements change as soon as the mission moves from first notice to maintained awareness. Detection is the moment the system first recognizes that something relevant may be present. Tracking is the process of maintaining that object’s position, motion, and continuity over time.

In practice, a system may succeed at the first task and still struggle with the second.
