| Abstract: | Intermodulation suppression for FH(frequency hopping) receiver is designed by selecting the intermediate frequencies and changing group of filters,local oscillation(LO) frequency,bandwidth of LO frequency under the condition that receiver configuration,sensitivity,dynamic range,instantaneous bandwidth and precision of frequency measurement are fixed.The methods of measurement for monotone and dual tone intermodulation suppression are provided as receiver works at FH mode based on intercept probability and false alarm probability are up to par.The results of measurement show that the performance of intermodulation suppression can meet the expectation of communication countermeasures. |
| Keywords: | FH receiver intermodulation intermodulation suppression method of measurement |
