Abstract:

A summary of propagation climatological data is compiled which is intended to aid Naval Weather Service personnel in forecasting and understanding the existing climatology of refractive-layer characteristics in the Point Mugu area. The Point Mugu area is defined as the immediate station and the area extending seaward to a radius of 75 miles. The following problems constitute the areas investigated and discussed 1 What radar wavelengths are affected by ducting layers 2 If ducting layers are not present, can increased radar ranges be expected for superrefractive conditions, or can decreased ranges be expected for subrefractive conditions at the transmitter site 3 What transmitter-antenna elevation angles can be expected to be affected 4 Where is the radar-lobe distortion radar hole 5 Is the ducting layer too high above the transmitter, thus causing the radar hole to be out of range and 6 What is the horizontal extent of each type of layer. The study provides an operational foundation for the dissemination of existing measurements of atmospheric refractive index. A secondary function is to fill the need for a training aid as a ready source of information about complexities of radar propagation forecasting in the local area. Author
