Abstract
A limited set of mine detection trials, using a 94 GHz Doppler Beamsharpening data gathering radar, are described. Measurements were made of arrays of HB876 anti-tank mines located on a tarmac runway and on grass. High spatial resolution radar images are presented with mines present and absent. The clutter statistics are summarized, and a method of thresholding the data using an Ordered Statistic Constant False Alarm Rate detection algorithm is described. The mine detection results are compared with theoretical predictions and it is shown that mines were clearly detected against the runway at the measurement range of 750 m. The poor detection results against the grass are explained in terms of radar speckle and signal to clutter ratio. Radar design techniques to overcome these limitations are described.
