Abstract :
Due to their system complexity and high component cost, stepped frequency continuous wave radars have not been popular in the ground penetrating radar industry. However, over the last decade the cost of RF technologies has decreased considerably, making it more feasible to make SFCW GPRs. This paper discusses the implementation and development of a low cost SFCW GPR using digital radio technology, a homodyne single channel receiver and a digital signal processor. The radar operates over a bandwidth from 490 MHz to 780 MHz and is capable of taking a single depth profile measurement using 256 frequency steps in less than 0.5 seconds. The results of field trials are also presented
