“…The SFCW sensor that has been built at IRCTR [1] consists of a transmitter, a receiver, an antenna system and a personal computer (PC), which includes a data acquisition system (DAS) and a user -friendly interface. The signal is generated within the transmitter starting from a direct digital synthesizer, which walks from 115 MHz to 360 MHz through 8 steps.…”

The use of electromagnetic waves for detection of shallowly buried objects has some advantages over other types of detection systems. The most important is the fact that the detection process can be remote controlled, so the risks associated with this activity can be minimized. Also an airborne radio sensor can scan a larger surface with a higher speed. Any detection process supposes a certain accuracy which has to provide the location of the object as precise as possible. In the case of an electronic device the interface between the propagation media and the device is assured by the antenna systems, which plays a critical role for the system resolution. The paper describes a simple procedure to create a synthetic aperture antenna by using the data acquired with a moving transmitting and receiving antenna system.

“…To verify this approach the International Research Centre for Telecommunications-transmission and Radar (IRCTR) in the Delft University of Technology has developed a number of GPR systems dedicated to landmine detection [2][3][4]. These systems have demonstrated high potential of developed GPR technology for classification of surface-laid and buried targets.…”

In this paper, the development of an UWB arraybased time-domain radar sensor is described. The radar sensor is designed to be used within a vehicle-mounted multi-sensor system for humanitarian demining. The main novelty of the radar lies in the modular approach, design of the antenna system and waveform of the transmit antenna feeding pulse. The radar has focusing capability via near-field beamforming in cross-scan direction and migration in along-scan direction.Index Terms -Video-impulse radar, ultra-wideband antenna array, landmine detection.

“…The International Research Center for Telecommunications-transmission and Radar (IRCTR) in the Delft University of Technology put considerable efforts in optimizing GPR technology for landmine detection [3]. The work resulted in development of two principally new GPR systems -multi-waveform full-polarimetric Video Impulse GPR [4] and Stepped Frequency Continuous Wave GPR [5].…”

Fully polarimetric measurements over a minefieldlike test site with video impulse ground-penetrating radar

et al. 2003

The results of the measurement campaign, which has been held recently at the test facilities for landmine detection systems located at TNO-FEL (The Hague, the Netherlands), are presented. The test facilities give an opportunity to evaluate system performance in different environment (such as grass, sand, clay, etc.) under controlled conditions. The test lanes contain various types of antipersonnel and antitank mines. In this campaign we used the Video Impulse Ground Penetrating Radar that has recently been developed in the IRCTR. The design of the radar allows us to perform simultaneous full-polarimetric measurements in two ultra-wide frequency bands. Furthermore, the scattered from subsurface electromagnetic field is measured in quasi-monostatic and essentially bistatic antenna configurations. The acquired during the measurement campaign data are of high quality in terms of time stability, radar positioning and signal-to-noise ratio. This has allowed to extract full-polarimetric target responses and to analyze them. The obtained results are of importance for target classification.
