Comparison of symbol-rate detector and radiometer intercept receiver performances in a nonstationary environment
The performances of radiometer and DMR (delay and multiply receiver) intercept receivers have been compared. Examples showing the detectability of direct sequence spread spectrum versus spreading ratio and noise fluctuation are given. Comparisons are also made between communicator performance and in...

Summary: | The performances of radiometer and DMR (delay and multiply receiver) intercept receivers have been compared. Examples showing the detectability of direct sequence spread spectrum versus spreading ratio and noise fluctuation are given. Comparisons are also made between communicator performance and interceptor performance. It is shown that the DMR can give superior performance in an environment with nonstationary interference. This is achieved at the cost of higher complexity at the detector. Some of this performance gain can be nullified if the communicator uses filtering to defeat the DMR. Which detector is most appropriate depends on the target signal and the cost complexity trade.< > |
