Radar Signal Generator and Receiver (RSG-RSR)
The RSG-RSR system contains Exciter and Receiver functionalities for S-Band radar. The system is con?gured in a 33U air cooled 19-inch rack. RSG and RSR are installed as independent Sub-racks. The rack is powered by AC 220V supply. The air-cooled 19” rack is housed in a shelter. Radar Signal Generator (RSG) generates TxDr, all LO clocks and clocks for ADC and DAC, based on dwell messages and timing information received from STM. Spot frequencies and LO1 are generated using Direct Frequency Synthesis technique which provides better spurious performance. IQ samples from Radar Signal Receiver (RSR) are sent to SP for signal processing. RSG-RSR system operates in two modes – Normal Resolution and High Resolution. High speed optical interfaces, using sFPDP protocol, are used for dwell commands and IQ samples. RS422 interface is used for timing information.
