Aug 27, 2013 · Clock Pulses Counter Based in my last post , I decided to modified a little bit the code and create a ' Clock Pulses Counter '. In-depth knowledge about SW development for real-time embedded systems. 2 Radar Signal Analysis and Processing Using MATLAB (1. Jaijo has 3 jobs listed on their profile. com Abstract: This contribution treats the simulation of pulse Doppler radar system by using PC and MATLAB Simulink. Radar Performance Radar Performance The actual performance of a weather system is a combination of many factors. and I downloaded the "soumekh. The duration of the pulse or the pulse-width, is defined between the half-power points of both edges. One must also: Ö Understand radar operations and design philosophy Ö Know how to select. MATLAB® scripts read the. In particular decorrelation phenomena have been analyzed, providing a performance evaluation and proposing estimation and compensation techniques to reduce their effects on the focused images (moving target clutter decorrelation, atmosphere phase screen and others). The simulator has been implemented through hardware represented in the AT computer interface card while the software was build with C++ language. automotive radar – a tale of two frequencies. The receiver bandwidth in this radar is wide such that it can acquire significant spectral components of the pulse. Since a short pulse requires a high peak power which is unattainable for many constraints such as voltage breakdown, dimension of waveguide etc, the radar system uses a longer pulse and pulse compression technique. Chapter 14 MATLAB Program and Function Name List This chapter provides a summary of all MATLAB program and function names used throughout this book.
