Improved Phased Array Radar/Sonar Simulation
Показать описание
The wave equation is simulated with the finite difference method using CUDA parallel programming in C++. A 64-element linear phased array transmits a directional pulse in the form of a Barker code. Return echos are analysed with a matched filter and the array elements are weighted with the cosine window. Results are integrated over several pulses to demonstrate beam-forming and scanning.
This simulation was calculated, displayed, and recorded in real time using using an NVIDIA GeForce GTX 570 graphics card.
