Abstract

The detection of buried objects using time‐domain free‐space measurements was carried out in the near field. The location of a hidden object was determined from an analysis of the reflected signal. This method can be extended to detect any number of objects. Measurements were carried out in the X‐ and Ku‐bands using ordinary rectangular pyramidal horn antennas of gain ∼15 dB. The same antenna was used as the transmitter and receiver. The experimental results were compared with simulated results by applying the two‐dimensional finite‐difference time‐domain (FDTD) method, and agree well with each other. The dispersive nature of the dielectric medium was considered for the simulation. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 31: 45–47, 2001.
