SIGNAL PROCESSING DEVICE, SIGNAL PROCESSING METHOD, AND SIGNAL PROCESSING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/023883
Kind Code:
A1
Abstract:
An attack determination unit (241) determines the presence or absence of an attack by a deception signal, by detecting, from a beat signal (S8), jitter caused by the attack by the deception signal. When the jitter has been detected by the attack determination unit (241), a countermeasure time information calculation unit (242) calculates tracking information (S11) after removing information on the distance and speed observed due to the deception signal. An information selection unit (243) selects tracking information to be used from the tracking information (S11) and tracking information (S9) generated from the beat signal (S8).
