How does the 4D Imaging Small-Target Radar differ from conventional marine radar?

The two systems have different design objectives and strengths. Conventional marine radar is well suited to longer-range, all-weather target detection and provides an overall picture of surrounding vessels and shorelines. The 4D Imaging Small-Target Radar focuses on close-range small-target detection and high-resolution perception.
By measuring range, azimuth, elevation, and velocity, the radar generates high-resolution point clouds that present target position, outline, and motion in greater detail. It offers advantages in separating adjacent targets, distinguishing vessels from shorelines, and continuously tracking small targets.

Can the 4D Imaging Small-Target Radar replace conventional marine radar?

No, nor is it designed to do so. Conventional marine radar remains essential for longer-range, all-weather navigational awareness. The 4D Imaging Small-Target Radar complements it with close-range high-resolution perception, small-target detection, and detailed imaging.
Used together, the two systems provide both wider-area navigational awareness and detailed close-range perception for berthing and unberthing, port operations, navigation in narrow waterways, and autonomous navigation systems.

Why do vessels need a 4D Imaging Small-Target Radar?

In ports, coastal waters, narrow waterways, and berthing or unberthing scenarios, vessels need to determine not only whether a target is present, but also its precise location, movement, and spatial relationship with shorelines and nearby targets.
Because of range and azimuth resolution limits and the effects of sea clutter, conventional marine radar may struggle to detect small craft, buoys, floating objects, and other weak targets consistently. Returns from adjacent vessels, targets, and shorelines may also merge, limiting the precision required for detailed ship handling.
Using high-resolution point clouds and target velocity information, the 4D Imaging Small-Target Radar provides more stable close-range detection and tracking while distinguishing vessels, shorelines, and adjacent targets more clearly. This supports berthing and unberthing, navigation in narrow waterways, port operations, and autonomous navigation.

Where can the 4D Imaging Small-Target Radar be used?

It is suitable for ports and terminals, narrow waterways, ferries and passenger vessels, offshore operations, unmanned surface vessels, and other scenarios requiring close-range small-target detection and high-resolution perception.
