    • A Field Programmable Gate Array (FPGA) system is provided to read input radar signals and produce an output for plotting a regular radar display on a pre-defined map to obtain an accurate and easy-to-read rendition of the position of a target being mapped by the radar. Analog radar signals received are converted to digital signals by an RSC. CFAR mechanism is used to condition the digital signals which are then compressed to create video frames by a B-Scope. The created video frames are stored in a DDR storage means via a DDR arbiter having a pre-determined number of read/write ports, each port having a pre-defined priority. The created video frames are blended with a synthetic video to produce a fused video by alpha blending technique. An alpha display provides non-interlaced scanning for raster display of the fused video at a pre-determined resolution.

    • A Field Programmable Gate Array (FPGA) system to read input radar signals and produce an output for plotting an aerial radar display on a pre-defined map to obtain a rendition of the position of a target being mapped. Analog radar signals received are converted to digital signals by an RSC. Received digital signal and radar control signal are used by PPI to create aerial scan video frames. The created frames are stored in a DDR2 SDRAM storage means via a DDR2 multiport controller having a pre-determined number of read/write ports, each port having a pre-defined priority. The created frames are positioned and resized in raster zoom-pan controller means and then blended with synthetic video generated by a host processor to produce a fused video by alpha blender using alpha blending technique. An alpha blender provides non-interlaced scanning for raster display of the fused video at a pre¬ determined resolution.
