A COMPARISON OF TWO WIDE-BAND INTERCEPT TECHNIQUES
Abstract
Two wide-open, multiple-band, crystal video intercept systems have been compared in an operational environment. The principal difference in the two systems was that one used the AN/SPS-8A radar antenna and the other the AS- 570/SLR ECM antenna. Both used conventional crystal video receiving techniques and a novel radar PPI display consisting of concentric rings to represent the frequency bands and attached radial spokes to represent intercept bearing. In addition, limited tests were made of (1) a proposed radar video tape recorder technique for display of radar information during intermittent radar operation, and (2) the usefulness of the intermittent radar technique to prevent detection by snooper aircraft. It is concluded that radar antennas in general are inherently not suitable for wide band intercept applications. This is because of their narrow rf transmission band, restricted (normally linear) polarization, and low rotation speed. These characteristics are not compatible with acceptable intercept receiver performance.
