A Nagajyothi, K Raja Rajeswari . Graphical User Interface based Signal Generator for Radar/Sonar Pulse Compression Codes. International Journal of Computer Applications. 82, 16 ( November 2013), 15-19. DOI=10.5120/14247-2325
A high – precision and stable signal generator with extremely high frequency is ideal equipment in radar signal processing. But in radar applications there is limitation on the devices, time, space and cost (in terms of value and maintenance) and is very high. To meet the demands of this special area, the paper designs such a signal generator based on Graphical User Interface in matlab which can be used for educational and research purpose. The results of the paper show that the signal generator is capable in generating various waveforms of the pulse compression codes. The performance of the codes is compared with the theoretical results which found to be accurate and can be used in wide variety of radar applications. Ambiguity Function (AF), Auto Correlation Function (ACF) and contour plots of the pulse compression codes are plotted via pop-up buttons without opening the m-file program because of the modular design. It provides the user an option of rotating and zooming of the obtained graphs and able to calculate the performance criterion of the selected pulse compression codes
