Abstract :
The authors prove that the output of a hard limit transponder with the input of Q-SS signals has no third band and fifth band intermodulation products though there are higher bank intermodulation products (IMP) which are very small and may be neglected. To solve the problem of the rapid acquisition of Q-SS signals, the authors discuss how to use the SAW convolver for the correlative processing of Q-SS signal, and the experimental result is given
