ABSTRACT:
The invention is a programmable frequency controller for a frequency agile adar system. The system comprises a microprocessor which includes clock generator, a front panel radar parameter input unit, a program memory, data memory, a front panel radar an input buffer port, a microprocessor data bus, an output buffer port, a front panel display unit, a radar data collection system, a radar synthesizer output buffer unit, a radar frequency synthesizer, and a frequency agile radar system with antenna. The control system operates, monitors, and collects operational data during operation of the frequency agile radar system. Input control parameters are preset at the front panel radar parameter input unit. Program memory contains preprogrammed computer control instructions for the microprocessor in performing control and management of operational data during radar operation. The data memory unit provides capability of storing and transferring data during operation of the system. The front panel display allows for the display of selected parameters for real time monitoring of the system's operation. The radar data collection system is comprised of high speed, multichannel, magnetic tape recorder units which record select data for further or later processing. Operation of the radar system by the microprocessor is controlled through the synthesizer output port and the frequency synthesizer. The frequency synthesizer receives operational command from the microprocessor, interprets these commands, and generates the control frequency cycle by which the radar system is to operate. Necessary control functions for operation of the system occur within the pulse repetition time, which can be as short as 20 microseconds.
