Specification for Radar Free-Space Detection Range and Free-Space Intercept Range Calculations
Abstract
General-purpose utility programs have been developed to calculate the free-space ranges of a pulse radar and an Electronic Support Measure (ESM) receiver. These utility programs are written in ANSI Fortran. The radar utility program allows the user to calculate radar free-space ranges for arbitrary radar cross-sections, for any probability of detection between 0.1 and 0.9, and for any probability of false alarm between 10 to the 12th power and 10 0.0001. A similar program to calculate the free-space intercept range for ESM receivers allows the user to input receiver sensitivity, transmitted power, and transmitter antenna gain to obtain a free-space intercept-range value. These programs are subroutines of simple driver programs the user can modify. The programs, as provided, will prompt the user to provide specific input values, and will print a list of the input values as well as the calculated free-space range value at the conclusion of the calculation of that range value. The equivalent one-way free-space path loss for isotropic antennas at the free-space range is also provided. This path loss value can be used with transmission-loss codes or diagrams to assess actual electromagnetic system performance in a real world environment.
