Preprocessing ? Pulse data acquisition ? Deinterleaving of pulse data ? Library matching ? Correlation and update of emitter status with previously received data ? Measurements of scan period/rate and type upon command ? Reporting emitter data and status ? Reporting pulse data for real-time displays ? Selects processing parameters such as bandwidth, threshold, CW definition and others ? Primary communications interface to/from the operator workstation The Signal Processing System has the following display types: ? System Set-up Displays ? Tabular Emitter Displays ? Graphical Emitter Displays ? Detailed Emitter Displays ? Real Time PDW Pulse Analysis Displays ? PDW Pulse Collection Displays ? Signal Intercept Report Recording and Playback Displays ? Library Editing Displays ? Built-in Test Displays ? RF/IF Displays ? DF Displays This system processor receives an RF input supplied by the user. Within the unit, the RF is converted to IF by a Microwave Tuner. The IF is digitized by a digital receiver which forms burst records of pre-detected data containing pulse information. Algorithms extract the pulse features from each pulse and store the data from each pulse in a Pulse Descriptor Word. The Pulse Processor Unit is a standard 5.25? high, 19? rack mount VME chassis containing a microwave tuner, a digital aperture VMW signal processor module and a system interface VME circuit card that provides for the system electrical interfaces. The digital signal processor module consists of a digital aperture PMC Module and an IF Conditioner PMC Module both mounted on a dual CPU Signal Board Computer. The Microwave Tuner requires 2 slots, the System Interface Board requires 1 slot and the Signal Processor Module requires 1 slot. Signal processing specifications relating to interpulse and intrapulse characteristics are presented in separate tables below. The performance requirements, unless otherwise stated, are for a 17 dB (minimum) input SNR signal.
