Surveillance position determining apparatus, surveillance position determining method, and computer-readable medium

A surveillance position determining method comprising:

• dividing map information stored in a memory into multiple cells in a grid on a horizontal plane, the map information including at least a predetermined surveillance target region;
• determining scores for respective candidate cells, the scores each being based on easiness of viewing from an own aircraft and difficulty of being viewed from a surveillance target that are quantified, and the candidate cells excluding multiple surveillance target cells included at least in the surveillance target region, among the multiple cells;
• and
• setting the surveillance positions on a basis of the determined respective scores of the candidate cells.

A non-transitory tangible computer readable medium having a program that causes, when executed by a computer, the computer to implement a method, the method comprising:

• dividing map information stored in a memory into multiple cells in a grid on a horizontal plane, the map information including at least a predetermined surveillance target region;
• determining scores for respective candidate cells, the scores each being based on easiness of viewing from an own aircraft and difficulty of being viewed from a surveillance target that are quantified, and the candidate cells excluding multiple surveillance target cells included at least in the surveillance target region, among the multiple cells;
• and
• setting the surveillance positions on a basis of the determined respective scores of the candidate cells.

A surveillance position determining apparatus comprising:
