Mie理论程序

这个程序可以计算给定点处的小区信号范围覆盖。-is program computes a map of visibility from a selected point on a topography. It has been written to help the search for radio relay best location. Because it considers only direct line of sight, it gives a good estimation for possible radio link for short distances only (less than 10 km), neglecting curvature of the Earth, Fresnel zone and atmospheric refraction on radio waves propagation. The program computes the relative elevation angle of the mask for each point (the angle is null or negative if the point is visible). The function needs a digital elevation model Z and associated (X,Y) vectors or matrices of coordinates (same unit as Z), position of the point (X0,Y0), the antenna height H0 (for instance 4 m), and the hypothetic antenna height Ha on each topography points (for instance 3 m). When no output argument is given, the function plots a map of the results (color map of mask angles, and blank for visible points, see example screenshot). The s

/* binarysearch() - A binary search implementation which takes the same * arguments as the C library function bsearch() provided by stdlib.h. It * searches the sorted array at address base, which has nmemb elements, each of * which is size bytes long. compar is a pointer to a comparison function. * The function compares two array elements, and returns a negative, zero, or * positive integer depending on whether the first array element is less than, * equal to, or greater than the second. */
