A Study on a Terrain Scan Data Generation Algorithm Using Peak Point Sampling-Methed

In this paper, a new method is proposed to shorten the runtime of a terrain scan data generation algorithm. The terrain scan data generation algorithm merges measured terrain data obtained by simulating the multiple beams radiation according to terrain scan commands, generating terrain scan data that reflects radar characteristics. The measured terrain data from each beam is generated by considering the radar cross section of terrain detectable from the beam and the distance from the terrain to the radar. The terrain detectable from the beam is determined by distinguished terrain inside the beam and visibility determination, and in these two processes, a grid-based visibility determination method with a long runtime was proposed A peak point sampling method with a shorter runtime and maintained performance compared to the grid-based visibility determination method is proposed. The runtime and performance of the peak point sampling method and grid-based visibility determination method are compared through simulation. The result of comparsion shows that peak point sampling method have the shorter runtime and maintained performance
