1. A scan conversion apparatus using a graphics processing unit (GPU), comprising:
an input unit configured to receive N-th azimuth information of a radar sampled with a sampling number, wherein N is a natural number; and
a controller comprising a central processing unit (CPU) and the GPU and configured to:
identify, using the CPU, the sampling number of the received N-th azimuth information;
compare, using the CPU, the identified sampling number of the received N-th azimuth information with a predetermined sampling number of a scan conversion;
in response to determination that the identified sampling number is different from the predetermined sampling number, perform, using the GPU, the additional sampling on the received N-th azimuth information;
generate, using the CPU, a texture map based on the additionally sampled N-th azimuth information;
generate, using the GPU, an N-th triangle based on a center coordinate of a circle; and
perform, using the GPU, the scan conversion by texture-mapping the texture map.
