Simulation of Complex Pulse Modulations
Abstract
Analysis of complex pulse modulations is essential to effective countermeasures. This report describes the various types of pulse modulation, discussed the development of a laboratory device for simulation of these signals, and illustrates the appearance of the modulated pulses on the most versatile signal analyzer (AN/SLA type) available at the present time. Results of this investigation verify the need for development of new techniques for analysis of signals of this type. The complex pulse generator described is a valuable aid in the laboratory as a signal source for checking operation of complex pulse demodulators, and in the field as a training device for operating personnel. By its use, the appearance of complex pulse modulations on typical intercept indicators, such as the type AN/SLA, can be determined; and it will thereby assist in classification of unknown signals.
