Abstract : Techniques for improving the performance of radar microwave links were evaluated. State-of-the-art modules such as a tunnel diode amplifier, balanced mixer, Gunn diode local oscillator, and a solid-state IF amplifier were procured and evaluated in the laboratory. Selected components were then tested in an operational system for 3 months, and recordings of received signal level on two adjacent links were correlated with existing weather conditions and system outages. The results of the field and laboratory evaluations indicate that significant performance improvement can be obtained by replacement or modification of certain components of the existing system.
