此外,由于本文详细描述了模拟的基本数学原理,它还可以作为雷达模拟的手册。该模拟器是作为一个独立的、跨平台的软件制作的,在Matlab环境中可以运行。该模拟器支持单态、双态和多态配置,包括遮蔽。地表模型使用修改后的冯氏模型来描述粗糙度、透明度和复杂反射率。天线模式采用通用的二维模型进行定义。文中还展示了该模拟...
Copy Code Copy CommandThis example describes the modeling of a 77 GHz 2-by-4 antenna array for Frequency-Modulated Continuous-Wave (FMCW) applications. The presence of antennas and antenna arrays in and around vehicles has become a commonplace with the introduction of wireless collision detection,...
Copy Code Copy CommandThis example shows how to simulate frequency-modulated continuous-wave (FMCW) interference between two multiple input multiple output (MIMO) automotive radars in a highway driving scenario. Missed and ghost targets caused by interferences are simulated and visualized. This example...
This example shows how to model an automotive adaptive cruise control system using the frequency modulated continuous wave (FMCW) technique. This example performs range and Doppler estimation of a moving vehicle. Unlike pulsed radar systems that are commonly seen in the defense industry, automotive ra...
Third, I am not sure if I am using 'fftshift' function right. Because when I increase the speed of the target, for example from 0 to 1, peak's position shifts to negative value (below zero). Forth, how do I define range and doppler resolutions and use them for x and y axis whil...
Namespace:phased Samples of FMCW waveform expand all in page Syntax Y = step(H) Description Note Starting in R2016b, instead of using thestepmethod to perform the operation defined by the System object™, you can call the object with arguments, as if it were a function. For example,y...

To run the simulation, execute themain.mscript in MATLAB or Octave. The images will be saved in the./imagesdirectory. octave main.m Installation Required Packages: Ubuntu 22.04 Octave 7.4.0 Control Systems Toolbox Signal Processing Toolbox ...
To illustrate how the algorithm works, consider the example shown below of the effect of chirp nonlinearity for two targets at different ranges. In the upper subplot, the green curve represents the time-frequency characteristic of the transmitted signal, which is linear except for a "kink" in ...
phased.FMCWWaveformassumes that all frequency modulations are linear. For triangular sweeps, the slope of the down sweep is the opposite of the slope of the up sweep. Double Triangular Sweep Copy Code This example shows how to sample an FMCW waveform with a double triangular sweep in which the...
