Abstract:
A radar scan converter coupled to a personal computer, comprising:an analog-to-digital converter, receiving an analog signal of a radar video and converting the analog signal of the radar video into a digital signal of the radar video;a radial buffer, coupled to the analog-to-digital converter to receive the digital signal of the radar video;a decimation filter, coupled to the radial buffer to decimate the radar video stored in the radial buffer according to a preset display range;a coordinate converter, to receive an AZ synchronous signal to calculate a polar coordinate of the radar video, and to convert the polar coordinate of the radar video into a Cartesian coordinate; andan overlay processor for mixing image, coupled with the decimation filter and the coordinate converter, to read a display memory in the personal computer according to the Cartesian coordinate generated by the coordinate converter, and to compare a pixel data read from the display memory.
