RADAR APPARATUS
First Claim
1. A radar apparatus for detecting around a ship, comprising:
- an unstable area detecting module configured to observe a variation in a signal level corresponding to detection data over a plurality of scans, obtain unstableness of the observed detection data, and detect unstable areas based on the unstableness;
a determining module configured to measure a size of each of the unstable areas and determine the unstable area as a small target object area when the size of the unstable area is below a given threshold;
a processing module configured to process the detection data corresponding to the small target object area to be emphasized when displayed, than the detection data corresponding to the other unstable area ; and
a display unit configured to display a processing result of the processing module.

Abstract
A radar apparatus (100) for detecting around a ship is provided. The apparatus (100) includes an unstable area detecting module (10) configured to observe a variation in a signal level corresponding to detection data over a plurality of scans, obtain unstableness of the observed detection data, and detect unstable areas (41, 42, 43, 44, 410, 420, 430, 440) based on the unstableness, a determining module (22) configured to measure a size of each of the areas and determine the area as a small target object area (41, 43) when the size of the area is below a given threshold, a processing module (6) configured to process the detection data corresponding to the small target object area (41, 43) to be emphasized when displayed, than the detection data corresponding to the other unstable area (42, 44), and a display unit (8) configured to display the processing result.
