UWB Radar Calibration Using Wiener Filters for Spike Reduction

Target identification with polarization dependent transfer functions

“…Since the calibration trigger target absorber material horn antenna pulse generator sampling oscilloscope signal processing algorithm contains convolution and deconvolution operations, Wiener filters for spike suppression are used. Further details about it can be found in [3].…”

“…As mentioned in section I, the calibration procedure proposed in [3] yields the transfer function of the target which is derived by the ratio of the received pulse from the target V T (ω) and received pulse from a well-known reference object V ref (ω) (both in the frequency domain)…”

“…Other studies [1], [2] have employed creeping waves on wires or impulse signatures of air planes. In this work based on [3] we propose a new procedure for determining the size of a target. In general, the RCS depends on several parameters: the frequency, the angle of the incident field and the polarization.…”

Novel integrated system calibration method for impulse ground penetrating radar

“…One example is the calibration method that removes the antenna coupling (Cheadle et al, 1999;Cheeseman and Huang, 2006). Hantscher et al (2006) calculate the impulse response function of the antenna with the aid of measurements from a reference target in order to eliminate the influence of the forward and reverse transmission of the antenna. However, the effect of multiple reflections was not taken into account.…”

“…The calibration based on S-parameters (Dong, 1985;Hauschild and Knochel, 1998;Mikhnev and Vainikainen, 2003;Nicolaescu et al, 2003) is a more effective antenna calibration method than methods that only remove direct coupled waves (Cheadle et al, 1999;Cheeseman and Huang, 2006) or only calculate the impulse response functions of antennas (Hantscher et al, 2006). The S-parameter calibration can more successfully eliminate the influence of most factors including multiple reflections.…”
