Title:
RADAR SIGNAL PROCESSING DEVICE
Document Type and Number:
Japanese Patent JP2611654
Kind Code:
B2
Abstract:
PURPOSE: To obtain a radar signal processing device for improving the detection rate of a target by effectively utilizing a filter where the number is limited in terms of the relationship with the number of bits.
CONSTITUTION: An MTI map is set by an MTI (Moving Target Indicator) map generator 1, an automatic clutter map is set by an automatic clutter map generator 2, a trigger pulse for stagger synchronization is generated by a synchronizer 4, and a specific filter coefficient which is different for each trigger pulse is output from a filter coefficient controller 3. By this filter coefficient, the filter characteristics of filters 8-11 are switched over and by a selection switch 5 and a switch 7 the transfer path of an input video signal is switched over. By switching over the filter characteristics of the filters 8-11 for each trigger pulse, filter characteristics are set to be compensated each other and the maximum signal of each filter is detected by a maximum value detector 16 as an output video signal.
