Design of Control and Interlocking System for a Typical Radar Transmitter

Abstract

The paper presents design and constructional features of CPLD based control and interlocking units for a typical MST radar transmitter. The conventional digital hardware used for controlling the radar transmitter and performing the interlock operations has been replaced by Xilinx’s XC9572C10PC84 CPLD device. The latest state of the art devices replace the front panel switches and LEDs display. This has resulted in miniaturizing the entire control and interlock subsystems. The necessary code is written in Verilog HDL. The newly designed system overcomes the design flaws in the earlier system hardware. The performance and results of the system have been verified with the simulation and real time testing at the plant. The unit testing is performed for more than four months with continuous operation of transmitter and the test report is highly encouraging
