Abstract
Conventional radar systems are rugged but prone to false echoes from various surrounding metallic structures which are always present in the industrial site. This paper presents a methodology for false echo mitigation in radar-based positioning system which is suitable for industrial conditions, specifically at steel plants. It can be used in various positioning requirements of rail-borne vehicles like overhead cranes and coke oven machines. In this method, the round-trip time of flight (RTOF) technique is used to measure the distance between two nodes. The echo signal is a frequency shifted active return, for eliminating false echoes, thus enabling distance measurement with very high degree of precision and accuracy even in a scattering environment. This method eliminates the problem of false echoes which is present with conventional radar systems. Using this method, the distance between the stations can be accurately determined over a range of 500 metres with precision in millimetres.
