RADIO WAVE EMISSION SOURCE DETECTOR AND RADIO WAVE EMISSION SOURCE DETECTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a radio wave emission source detector capable of downsizing.;SOLUTION: A radio wave emission source detector 10 comprises: antenna elements 12; an AD conversion part 21; a virtual array antenna signal generation part 22; an incoming direction estimation processing part 24; an imaging processing part 26; an imaging part 15; an image combining processing part 27; and a display device 17. The AD conversion part 21 generates reception data including phase information at each time of reception of each of multiple radio waves received by the antenna elements 12 at multiple locations. The virtual array antenna signal generation part 22 regards that the multiple radio waves are received at the same time and corrects the phase information so as to generate multiple virtual array antenna signals corresponding to the multiple locations of the antenna elements 12. The incoming direction estimation processing part 24 estimates a radio wave emission source on the basis of the multiple virtual array antenna signals. The imaging processing part converts the estimation result into a two-dimensional image and the image combining processing part 27 combines the two-dimensional image and an image acquired from the imaging part 15. The display device 17 displays this composite image.;COPYRIGHT: (C)2014,JPO&INPIT
