  • Patent number: 5381156
    Abstract: The present invention is a Multiple Target Doppler Tracker which tracks a plurality of components, including debris and submunitions of a munition burst apart above the ground. A plurality of transmitters transmits constant frequency (CW) signals towards the burst event of the munition and a plurality of receivers receive the signals reflected from the components. The signals received by the receivers are processed into frequency spectra. The spectra are analyzed to determine the path of a selected number of components. Using the path information the selected components are tracked with tracking devices.
