Calculation device for radar apparatus, radar apparatus and calculation method

摘要

There is a calculation device for a radar apparatus which is configured to specify a direction of a target based on a reception signal of an antenna. A calculation unit is configured to calculate a relative displacement magnitude in a lateral direction of the target relative to a traveling direction of a moving object having the antenna mounted thereon, from data of the target position-measured by the reception signal while the moving object is moving, and evaluate a relative inclination between a reference axis of a scanning direction of the radar apparatus and a reference axis of the traveling direction of the moving object, based on the displacement magnitude.

1. A calculation device for a radar apparatus that is configured to specify a direction of a target based on a reception signal of an antenna mounted on a moving object, the calculation device comprising:
a calculation to processor configured to:
calculate a relative displacement magnitude from a lateral direction of the target relative to a traveling direction of the moving object using data representing the position of the target that is measured by the reception signal while the moving object is moving;calculate an average of relative moving speeds in the lateral direction of a plurality of targets relative to the traveling direction of the moving object; andevaluate a relative deviation between a reference axis of a scanning direction of the radar apparatus and a reference axis of the traveling direction of the moving, object based on the displacement magnitude.
