A computerized method (called SIGFRID) to simulate the amount of frequency-hopping interference in a receiver subjected to a number of interfering transmitters in a cosite situation was developed a few years ago. The method handles full scenarios, including friendly and hostile distant transmitters, jammers, ambient noise, and propagation characteristics. Modeling of important receiver and transmitter properties to allow analysis of densely colocated radios, as encountered in army vehicles and command posts, is included. In the present work the author considers the cosite modeling and its application to the analysis of improvements in cosite performance achieved by the PROFFAR cosite filter. It was shown that, using the facilities of SIGFRID, the improvement achieved by using PROFFAR can be readily demonstrated by subjecting a laboratory radio link to the simulated interference
