The introducing of satellite waves propagation simulation otherwise process in the ground neutral atmosphere experiencing occultation

In order to carry out remote sensing and atmospheric parameters to estimate and predict Weather conditions and natural disasters and recognition of the atmosphere surrounding the earth aerospace designing and making space terminals and utilizations for the use of efficient equipment in this field Several studies with different methodsand scientific theory have been conducted. With the development of these technologies with modern methods thestudy of the atmosphere instead of previous methods such as thermometer and hygrometer and radio sound data processing or flight airship, is founding and developing. One of the ways was introduced in 1960 and has been used in recent years in this area and to date has been the development of Radio occultation method. In this scenario satellite signals after the free space between the atmosphere and the Earth's atmosphere reached orbital position itself to various atmospheric layers after it passes through the atmosphere. Every part of the atmosphere effects on the signal, Its effects on the ionosphere layer of ions to Solar storms and deep the effects of the atmosphere and atmospheric factors such as pressure, temperature, humidity, refraction, change the signal and its specifications such as amplitude and phase and change its path. With the introduction of the geometry of the event that is described in this document and application form for mathematical and Helmholtz waves equations and analysis them we can check and simulate the wave behavior When the transmitter satellite sends it until a receiver receives it
