Abstract
A surrounding monitoring radar device includes a signal generation unit, a spectrum generation unit, a cycle setting unit, a learning unit, and an update unit. At an update timing, the update unit updates a determination reference to a learned value calculated by the learning unit. the learning unit is configured to: set the learning value to an initial value at a start timing of the learning period; compare the learned value with a value of a noise floor of the generated frequency spectrum during the learning period; and update the learned value to the value of the noise floor upon the value of the noise floor being smaller than the learned value.
