In this improved simulation, I recreate the simulation seen in my previous video [ Ссылка ] This version has improved simulation speed and signal processing resulting in higher quality results with half as many sensors compared to the previous video.
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.
