Signal Properties and Target Models in the View of Target Classification at a Surveillance Radartest can be performed for classification purposes. The statistical behaviour of the coherent signal of airplanes is derived from measured data and an example of a classification test between two types of airplanes can be given.

Side-Looking Radara method for detecting objects such as aircraft, vehicles or ships; and to that extent he would be correct. He might even add that other echoes from sea, clouds, rain or land was something called clutter to be eliminated as effectively as possible.

On the Influence of Atmospheric Refractive Index Irregularities on the Resolution Performance of a Ritation to system performance is constituted by the propagation medium itself. In order to optimize the radar performance under the adverse conditions imposed by the atmosphere one has to understand the detailed nature of the atmospheric phenomena, and one needs information about the extent to which the atmospheric limitations prevail.

On the Evaluation of Doppler Spectra for Radar Cross Section Analysis and Target RecognitionAn analysis of the Doppler frequency spectrum of the radar echo from a moving target is given, showing the relationship between the location of the scattering centers on the target and the spectrum. In addition a scheme is presented, that describes how to get an image of the target from the Doppler spectra.
