A method to predict the statistics of clutter loss for earth-space and aeronautical paths

This Report describes methods for predicting what is often called “clutter loss”. In the context of radio, the term “clutter” may have originated with the development of radar, since unwanted returns on a radar screen are also termed clutter. In general propagation modelling, clutter loss means losses due to objects which are on the ground but which are not the ground itself. In this context, “clutter” most often means buildings or vegetation.

This Report covers only losses due to urban or suburban clutter. Within this classification, any manmade objects can be included, particularly those of sizes omparable to buildings, such as bridges.
