Recording GPR data by means of a video camera recorder

A technique is presented for recording synchronized radar images and a video record of antenna position. This requires a GSSI Model 38/39 video display unit (VDU) or equivalent and a video camera recorder (camcorder) possessing a high fidelity stereo sound track. For this system, a continuous history of antenna position is recorded on the video channel; and simultaneously, radar data is recorded on the audio track. This permits the precise correlation of radar events with antenna position. The resulting data set can be viewed on dual monitors or on a single monitor with "picture in a picture" capabilities. As with other recording systems, the radar data can be down loaded directly into a computer for processing.
