Development of a Terrain Scan Data Generation Algorithm Using DTED

An algorithm is proposed for generating phased array radar terrain scan data from a simulated radar. To obtain simulated radar terrain scan data, it is assumed that the radar beam is scanned sequentially within certain azimuth and elevation areas. From this assumption, the radar terrain scan data are generated by integrating the detected information from each radar beam. The algorithm for simulating terrain scan data of the radar largely comprises two parts. One part of the algorithm generates terrain scan information from individual beams. The other integrates the scan information of individual beams into entire scan data. Although the proposed algorithm has some limitations, it provides a reasonable result that reflects the characteristics of an actual radar. Furthermore, the proposed algorithm is expected to have an impact on terrain following (TF), which needs accurate terrain scan data to generate a precise terrain profile.
