The evaluation of radar signatures of buried objects for three experimental ground penetrating radar setups will be addressed in this paper. The contribution will present corresponding results and experiences. The performance of the imaging capabilities of the designed radar system will be assessed by reconstruction of complex shaped test objects, which have been placed within the ground. The influence of system parameters of the ground penetrating radar have been varied systematically in order to analyze their effects on the image quality. Among the modified parameters are the step size in transverse plane, height of the antenna over ground, frequency range, frequency points, antennas and varying instrument settings. A signal processing technique based on synthetic aperture radar has been applied on the measured raw data. The focus radius around a specific target has been analyzed concerning the compromise between image quality and processing time. The experiments demonstrate that the designed ground penetrating radar systems are capable for detection of buried objects with high resolution.

Some 24GHz radar signal features are introduced in this paper for a reliable recognition of pedestrians and vehicles in an arbritary traffic situation. It examines in particular the Doppler spectrum and the range profile.

In this paper hardware and software aspects of detection and localization of people by their breathing are discussed. Separately, the problem of non-stationary clutter is considered. All the proposed algorithms are supported by measurement examples.

One of non-cooperative illuminators recently considered for passive radar applications is the DVB-T (Digital Video Broadcasting - Terrestrial) station. The thumbtack ambiguity function of the DVB-T signal in addition to being stationary makes such signal a good candidate for such applications. However, certain ambiguities in its ambiguity function necessitates certain issues to be carefully considered when DVB-T signals are to be utilized. In this paper, after studying the origins of these ambiguities, we propose special processing schemes to resolve them.
