Abstract

This project presents the optimization method for Nap-of-the-Earth. The Nap of the Earth (NOE) mode is the most exciting, most dangerous, and is typically the slowest. It is used by military aircraft to avoid enemy detection and attack in a high-threat environment. NOE is used to minimize detection by the ground-based radar, targets and the control system. The Radar Altimeter or Terrain-Following Radar system, Terrain Awareness and Warning system is used to detect the obstacles during flying in NOE flights. Here, while the flight is at nap of the earth operation, the speed and the altitude must be slow as already determined. The terrain following radar maintains the altitude from the ground level. So we analyze the problem to increase the performance of the aircraft by ranging the terrain by some modes of the Terrain Avoidance and Warning System which is given by ICAO, UKCA, EASA, and FAA. Further to this, different TAWS modes of operation, explanation of mode selection and advancement in TAWS are explained in detail. In this paper, MATLAB programming is done for some modes of TAWS operation and the simulation of flight path for the excessive terrain. Closure rate from mode 2 operation of flight is also done.
