Title:
INTERFERENCE SUPPRESSION DEVICE AND INTERFERENCE SUPPRESSION SYSTEM
Document Type and Number:
Japanese Patent JP2015227824
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To stably suppress deterioration in performance and function of a radar system resulting from synchronism interference, and enable a sweep integration effective for improvement in search performance to be applied with high accuracy, regarding an interference suppression device and an interference suppression system that suppress an interference wave arriving from outside in the radar device.SOLUTION: An interference suppression device includes: blocking means that discriminates a row of range cells, which are indicated by radar signals arriving in order of sweep and whose orders are identical, into blocks comprising a predetermined number of consecutive range cells; and in-block interference suppression means that executes interleaving in the unit of the range cell for each block, and suppresses a range cell having correlation with other range cells smaller than a predetermined lower value.
