Title: Direction finder
Inventor: OHASHI YOSHIMASA
IPC: G01S13/02
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To obtain the number of snapshots larger than the number of pulse hits for a target and to reduce an observation time required for measuring an angle of the target by using a wide-band receiver with a wider band as compared with the band of a transmission pulse. SOLUTION: A transmission pulse is transmitted and is radiated into the air by a transmission antenna 2. An electronic wave being reflected by a target is received by reception antennas 4-1-4-M and a signal is amplified by wide-band receivers 5-1-5-M, respectively, is subjected to frequency conversion, is synchronized with a trigger pulse from a controller 1, and is sampled for a purality of times. Data by the number of snapshots are inputted to a covariance matrix calculator 6. An inherent value/inherent vector calculator 7 calculates an inherent value and an inherent vector from a covariance matrix. Then, a mode vector calculator 8 calculates a mode vector corresponding to a virtual target based on the arrangement of reception antennas 4. Then, a noise part space projection length calculator 9 projects the mode vector and calculates a projection length.  A projection length minimum value calculator 10 calculates a direction where the virtual target is placed when the projection length being outputted from the noise part space projection length calculator 9 is minimized.
