Flying body and program
View Patent ↗A flying body includes an observation data generation unit that generates observation data on the basis of radio waves received by a radar, an image generation unit that generates an image representing a monitoring space on the basis of the observation data generated by the observation data generation unit, and a detection unit that detects a detection target on the basis of the image generated by the image generation unit.
1. A flying body comprising:
a synthetic aperture radar; and
a field programmable gate array (FPGA) configured to:
generate observation data on the basis of only radio waves received by the synthetic aperture radar;
generate an image representing a monitoring space on the basis of the generated observation data; and
detect a detection target on the basis of the generated image, wherein
the monitoring space includes a sea area, and
the detection target includes a vessel in the sea area.
2. The flying body according to claim 1 , wherein the FPGA detects the detection target through binarization of the generated image.
3. The flying body according to claim 1 , wherein the FPGA detects a target estimated to be the detection target, as the detection target, from candidates for the detection target in the monitoring space on the basis of a plurality of parameters stored in advance.
4. The flying body according to claim 1 , wherein
the FPGA trims a partial image representing a region of a predetermined shape centering on the position of the detection target from the generated image, and
generates the trimmed partial image as a transmission image.
