Title:
RADER SYSTEM
Document Type and Number:
Japanese Patent JP2023042899
Kind Code:
A
Abstract:
To provide a rader system capable of updating correction value even after being mounted on a movable body.SOLUTION: A rader system mounted on a movable body includes: a transmission/reception processing part 41 which is provided with a plurality of at least one of transmission antennas and receiver antennas, transmits a transmission signal from the transmission antenna, and acquires a differential signal indicating frequency difference between a reception signal received by the receiver antenna and a transmission signal; a signal processing part 42 which determines a reference value to be at least either a phase or amplitude at a predetermined reference part of a movable body according to a differential signal as a reference and determines collation value that is at least either the phase or amplitude at the reference part and corresponds to the reference value according to a differential signal to be corrected; and a correction value update part 43 which updates correction value correcting a differential signal to be corrected on the basis of the reference value and the collation value.SELECTED DRAWING: Figure 3
