A non-transitory storage medium storing computer program for assisting in setting a radio wave sensor configured to detect an object on a road, the computer program causing a computer to execute a process comprising:
- acquiring a detection result obtained by the radio wave sensor detecting the object on the road;
- determining an exclusion candidate area in a coordinate space based on the acquired detection result, the exclusion candidate area being a candidate for an exclusion area to be excluded from a detection target of the radio wave sensor, the coordinate space being set in the radio wave sensor;
- causing a display device to display the determined exclusion candidate area;
- and
- determining, as the exclusion area, the exclusion candidate area displayed on the display device.
