Abstract:
1. A signal processing apparatus that performs an object detection process of detecting object data with respect to peak signals which indicate a difference in frequency between a transmitted signal of which the frequency is changed in a predetermined period and a received signal which is obtained by receiving a reflected wave that corresponds to a transmitted wave which is based on the transmitted signal and is reflected from an object, by deriving the peak signals in a first period where the frequency of the transmitted signal ascends and in a second period where the frequency of the transmitted signal descends and by pairing the peak signals in the first period and the second period, the signal processing apparatus comprising: a continuity determination section that determines a continuity between the object data and past object data detected prior to the object data; a moving object data detection section that detects among the object data, newly detected moving object data that is determined by the continuity determination section as having no continuity with the past object data; a positional relationship detection section that detects a positional relationship between the moving object data that is detected by the moving object data detection section and other object data; and a data determination section that re-pairs the moving object data if one object data among the other object data has a predetermined positional relationship with the moving object data, the predetermined positional relationship being a positional relationship in which the other object data exists within a determined area that is prescribed by the position of the moving object data.
