[Object] To appropriately evaluate reliability of a reception signal.[Solving Means] A signal processing unit 20 includes a first integration unit 21, a Doppler detection unit 22, and a comparator circuit 28 as a reliability index calculation unit. The first integration unit 21 intermittently integrates a pulse train corresponding to a reception signal by using two systems and obtains two pieces of integrated data. The Doppler detection unit 22 divides each of the two pieces of integrated data into a plurality of range bins in time series, obtains a relationship between a frequency and intensity in each range bin for each of the two pieces of integrated data, and detects a Doppler shift amount from the relationship. The comparator circuit 28 calculates a reliability index of the reception signal by comparing the Doppler shift amounts (wind velocity values) of the two pieces of integrated data.
