ABSTRACT:
A Doppler compensated PSK signal processor which receives a plurality of sages from a sensor array and decodes each message for further data processing. The signal processor compensates for the Doppler shift in the message frequency due to the velocity differential between the transmitting vehicle and the sensor array. The message is decoded for a valid identification code from which is derived a time mark related to a specified system time to provide range and direction information for the identified transmitting vehicle. The telemetry data in the message and the time mark are output to a data processing system on an interrupt basis to provide tracking and data analysis for the transmitting vehicle.
