Abstract:

A number of experimental component and circuit techniques which are applicable in reducing the effects of high level interference on receivers have been developed and evaluated. An experimental receiver covering the frequency range 225400 Mc, incorporting many new RFI reduction techniques has also been developed. Areas of research included a band reject filter, capacitor and voltage tuned helical resonators, signal phase cancellation techniques, receiver designs and antenna techniques. The band reject filter and phase cancellation device were designed to be compatible with the R-361A communications receiver and the experimental receiver. The hollow, dielectric rod antenna was developed and investigated as a new approach for control of beam widths and angular location of pattern nulls. Modifications were also incorporated in the R-361A receiver to make it less susceptible to adjacent and to co-channel interference. Author
