摘要：

In order to separate buried land mines from clutter a multi-channel stepped-frequency ground penetrating radar has been developed. The system operates over the frequency band 800 MHz to 2.0 GHz. The radar incorporates advanced digital signal processing and radio frequency integrated circuit components. It uses an all-digital modulator coupled with a coherent digital quadrature receiver for making precise magnitude and phase measurements. The control interface to the radar consists of an Ethernet TCP/IP link. A parallel bank of transmit-receive antennas is used to achieve cross track sampling. System motion is used to achieve along track data sampling. Synthetic aperture nearfield beamforming techniques are used to image buried objects. The system is designed to detect shallowly buried metallic and non-metallic mines. A system overview is presented and results from data collection exercises are included. Images and analysis of data from a mine lane is presented.
