Radar Automatic Target Recognition (ATR) and Non-Cooperative Target Recognition (NCTR) ISBN: 9781849196857
For commercial ship traffic the automatic identification system (AIS) is obligatory for all vessels above a certain size and thus warrants their cooperative classification and even identification. However, for smaller craft and especially for non-coo

Algorithms for automatic target recognition and image intelligence have to be trained on the largest possible data base. A way to avoid excessive and costly measurement campaigns is to insert targets that were measured in a tower/turntable configurat

Based on measurements of a ship at 17 GHz and on several simulated ships at 35GHz it is demonstrated how multipath changes the range profiles that form a basis for the construction of ATR features for ship classification. The fluctuation of range pro

A high resolution imaging millimetre wave SAR delivers three key parameters important for precision farming applications, namely range, reflectivity and polarization state. The reflectivity gives information upon the type of crop and its humidity. Es

Automatic Target Recognition XIX.
Fully polarimetric radars that use polarization diversity on transmit and receive and thus provide the full scattering matrix, are subject to effects like cross-talk and channel imbalance. These distortions have to be eliminated by means of a polarim

This paper presents the analysis of high resolution millimeter SAR clutter data, measured in a joint Swiss-German flight campaign. The generalized Gaussian function and the Kolmogorov-Smirnov test are considered to test the hypothesis of Gaussian clu

To have an appropriate data base for the development of non-cooperative target identification techniques, airborne measurements were conducted with the mmW-SAR-system MEMPHIS over agricultural terrain with a variety of different fields and canopies o

The MEMPHIS polarimetric SAR is able to operate simultaneously at X-, Kaand W-band. After a detailed technical description, several examples are given to demonstrate its capabilities in the side-looking mode, in forward squinted Doppler beam sharpenu

A method is presented to achieve large bandwidths with a synthetic chirp waveform adequate for short transmit pulses, which are typical for all millimetre-wave-radar applications using solid state transmitter stages. The usual 'stretch' processing fo
