Radar land clutter measurements at frequencies of 9.5, 16, 35, and 95 GHz

A series of measurements of radar backscatter from foliage and other natural objects have been made at frequencies of 9.5, 16.5, 35, and 95 GHz. The geometry of the experiments and the equipment were chosen such as to provide data useful to the equipment designer in the choice of operating frequency for his particular mission. Amplitude statistics for both horizontal and vertical polarizations were obtained. Non-coherent spectral measurements and correlation properties were investigated in detail as functions of frequency, incident angle, and windspeed. Limited comparisons are made between previous measurements and analyses and the current experimental results, and certain properties of the results are discussed in relation to the phenomenology of land clutter. Extensive summaries of the data obtained are included as a part of the report.
