1. An embedded multi-functional preprocessing input data buffer in radar system for receiving data and outputting the data to a module output data bus, the embedded multi-functional preprocessing input data buffer in radar system comprising:

  • a clutter lock loop and multiplication circuit, selectively executing an coefficient multiplication or a clutter lock loop operation for the received data according to a working mode of a radar system;

    a mode selective multiplexer coupled to the clutter lock loop and multiplication circuit for receiving the data and selectively outputting data of the clutter lock loop operation;

    a dual-port memory coupled to the mode selective multiplexer for receiving and temporarily registering the data processed; and

    an output multiplexer coupled to the dual-port memory, the output multiplexer comprising a plurality of output channels, selectively outputting the data temporarily registered in the dual-port memory via one of the output channels according to the working mode of the radar system.
