Title: INTERFERENCE COUNTERMEASURE DEVICE
Abstract:
In the present invention, a countermeasure unit (S130) generates a countermeasure signal by subjecting a non-countermeasure signal acquired from a laser sensor by an acquisition unit (S110) in each processing cycle to interference removal processing for suppressing the influence of radio wave interference. An analysis unit (S120, S140) carries out frequency analysis processing using the countermeasure signal when an operation mode is an interference mode and using the non-countermeasure signal when the operation mode is a normal mode. A determination unit (220) determines whether there is radio wave interference according to the analysis results of the analysis unit. A switching unit (S210, S230-S250) switches the operation mode to the interference mode when the operation mode is the normal mode and the determination unit determines that there is interference and switches the operation mode to the normal mode after a state in which the operation mode is the interference mode has continued for a fixed number of processing cycles.
