Timing Signal Generator for High Frequency Radar

Abstract

In a radar application, Time Signal Generator (TSG) is used to generate timing and control signals which helps radar to operate in different functions. The functions include tracking, detection, and hold mode. Timing Signal Generator is the heart of radar applications. Timing Signal Generator is the main part of radar application, which is responsible for synchronization between Transmitter and receiver for the transmitted signal. In this work, an implementation of timing signal using a Hardware Description Language (HDL) language-based state machine which is responsible for enabling Direct Digital Synthesis and Analog to Digital Converter in the Transmitter and receiver window. Timing Signal Generator implementation on Field Programmable Gate Array is preferred as the entire Timing signal generator unit can be assembled on a single Field programmable gate array chip, and conditional modification can be performed remotely, which is cost-effective. Timing signal generator generation begins by providing an arbitrary frequency and phase signal configuration to DDS-AD9854 from Field programmable gate array. Direct digital synthesis block generates a single-tone signal and Binary Phase Shift Keying signal and a chirp signal based on an input arbitrary signal sent by ZYBO-7010 FPGA.
