Aircraft Suspicious Vessel Detection via Radar and Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aircraft systems are limited in identifying suspicious vessels from mid-air, as the search range for suspicious vessels is restricted to a small region surrounding the own vessel, leading to potential missed identifications.
Innovation Solution
An aircraft equipped with a vessel checker, image generator, and information transmitter, utilizing a marine search radar and automatic identification system to identify and photograph suspicious vessels, determining their appearance and behavioral characteristics, and transmitting this information to an external apparatus for verification.

1Area of stationary object
If the search range for suspicious vessels is limited to a small region surrounding the own vessel, then the detection process is simple and quick, but the search coverage is insufficient leading to missed identifications
Solution Approach 1:
The detection system is segmented into multiple functional units: a vessel checker for initial identification, an image generator for photographing, an appearance determining unit for analysis, and an information transmitter for communication. This segmentation allows the system to expand search coverage while maintaining manageable complexity through modular design.
Solution Approach 2:
The system transitions from traditional two-dimensional radar detection to three-dimensional detection by incorporating aerial photography and image analysis. The image generator captures visual data from the air, adding a new dimension to vessel identification that expands effective search range without proportionally increasing system complexity.
2Measurement precision
If the aircraft approaches the suspicious vessel candidate to photograph it, then the appearance identification accuracy is improved, but the time and energy consumption increase
Solution Approach 1:
The vessel checker performs preliminary identification of suspicious vessel candidates using radar and AIS data before the aircraft approaches. This preliminary action filters out normal vessels, so that when the aircraft does approach, it is only for confirmed suspicious candidates, reducing overall time and energy consumption while maintaining high identification accuracy.
Solution Approach 2:
The system uses feedback from the appearance determining unit to guide further actions. If the appearance analysis confirms suspicious characteristics, the system triggers information transmission and alert procedures. This feedback mechanism ensures that time and energy are invested in detailed observation only when necessary, optimizing the balance between accuracy and resource consumption.

AI summary
An aircraft includes a vessel checker, an image generator, an appearance determining unit, and an information transmitter. The vessel checker identifies a suspicious vessel candidate by comparing a marine vessel detected by a marine search radar with a marine vessel transmitting data with an automatic identification system. The image generator generates an image by photographing the suspicious vessel candidate after the aircraft approaches the suspicious vessel candidate in accordance with a route for approaching the suspicious vessel candidate. The appearance determining unit determines whether the suspicious vessel candidate in the image has an appearance characteristic of a suspicious vessel. The information transmitter transmits, to an external apparatus, information indicating that the suspicious vessel candidate has the appearance characteristic of the suspicious vessel if the suspicious vessel candidate has the appearance characteristic of the suspicious vessel.
