Description
Tests solely designed to test performance of spacecraft communication and ranging equipment under conditions of severe fading are usually impossible to perform, and when possible they are of too short duration to allow system modification to improve performance.
This paper describes a fading channel simulator which is readily constructed and flexible in operation. By use of this simulator communication and ranging equipment can be tested and optimized for operation during periods of severe fading.
The fading channel simulator described in this paper gives fading rates varying from about 2 to 30 cps.
Frequency and time scaling of the problem can be used if the fading rates of the channel to be simulated are outside this range .
