An experimental system for automatic radar target detection and digital coded plot extraction and transmission

The system provides means for the automatic detection, extraction and digital encoding of the search plot data available from 2-dimensional radar equipments. Conversion from polar to Cartesian co-ordinates is effected, and the encoded Cartesian plot data are transmitted for remote use over long distances using a single telephone circuit. Full radar accuracy, resolution and data are maintained. The local or remote coded plot data are suitable for decoding and display or for direct insertion into a digital computer programmed for filtering, plot correlations into tracks, etc.
