  • Patent number: 6756935
    Abstract: A method, apparatus, and system for automatic detection of targets from radar data are disclosed. Ground moving target indicator radar is used to collect radar data which is then filtered to suppress intensity of the clutter ridge. For each working point in a set of radar data, a working first-sense circular transmit/first-sense circular receive radar cross section, a working first-sense circular transmit/second-sense circular receive radar cross section, and a working asymmetry angle are calculated from a scattering matrix, then analyzed to classify the working point as a target point or a clutter point. This analysis suitably is performed by comparing data calculated for each working point to basis data collected in a look-up table in which combinations of a first-sense circular transmit/first-sense circular receive radar cross section, a first-sense circular transmit/second-sense circular receive radar cross section, and an asymmetry angle have been classified as target points or clutter points.

  • Patent number: 6750805
    Abstract: A method, apparatus and computer-readable medium having stored thereon instructions for automatic detection of desired targets from radar data are disclosed. For each working point in a set of radar data, from a scattering matrix derived from collected radar data, a working total radar cross section and a working asymmetry angle are calculated. The working total radar cross section and the working asymmetry angle are then evaluated to determine whether the working point should be classified as a target point or a clutter point. The method and apparatus suitably may employ a two-dimensional table of total radar cross sections and asymmetry angles previously classified as signifying target points or clutter points. Reading from the look-up table, the working point is classified as a target point or a clutter point.

  • Patent number: 5588598
    Abstract: An improved method of recovering recyclable materials from commingled recyclables is described as well as apparatuses for doing same. Ferrous materials recovery is achieved using the unique combination of a magnetic belt and a vibratory conveyor. Other materials are then separated with a light/heavy separator which uses finger screen, air knife, and vibratory means to separate glass from plastics and aluminum prior to conventional handsorting operations. Excess glass unsuitable for recovery is introduced into a trommel processing loop wherein contaminates are removed and the glass reduced to a particulate useful in the production of glasphalt and aggregate. Air emanating from the air knife is filtered in an improved gravity separator for reintroduction to the light/heavy separator.
