Title:
SIMULTANEOUS MULTI-TARGET GUIDING SYSTEM
Document Type and Number:
Japanese Patent JP2689889
Kind Code:
B2
Abstract:
PURPOSE: To provide a simultaneous multi-target guiding system in which the number of airframes to be simultaneously guided can be increased and antidisturbance can be improved.
CONSTITUTION: A ground phased array radar 1 searches targets 3a-3c to obtain their position and speed information, and radiates electromagnetic waves having different frequencies f1-f3 to the individual targets 3a-3c invading simultaneously. A fire controller 2 calculates a Doppler frequency to be received by flying airframes 4a-4c according to the position and speed information collected by the radar 1 and the frequencies. The airframes 4a-4c have local oscillators for setting reflected frequencies from the targets calculated by the controller 2 to receivable state. A communication link 5 combines the frequency information for recognizing the calculated result of the controller 2 with the airframes 4a-4c with data.
