Figure 3.7 Typical radar returns PSD when clutter and target are present 16 Figure 4.1 Graphical interface to MATLAB Workspace 20 Figure 4.2 Creating new M-file in MATLAB 21 Radar system design, simulation, and analysis is complex because the design space spans the digital, analog, and RF domains. RF Blockset is used for modeling the RF transmitter and receiver sections. The effective transmitted power of the radar system is 5 kW. Radar system engineers often need to simulate the clutter return to test signal processing algorithms, such as STAP algorithms. Surface clutter refers to reflections of a radar signal from land, sea, or the land-sea interface. For the Aerospace Defense industry, this is an important multi-discipline problem. When trying to detect or track targets moving on or above the surface, you must be able to distinguish between clutter and the targets of interest. Radar or EW engineers use MATLAB and Simulink to model wave propagation, clutter and jammer and interference, target motion with constant velocity and acceleration, and target cross-section. First, define the components of a radar system. This example shows how to use Simulink® to suppress clutter and jammer interference from the received pulses of a monostatic radar. Best Answer. The sample rate is 1 MHz, and the PRF is 10 kHz. GPU Clutter Simulation of Radar System with Known Power. simulation of clutter signal based on real signal characteristics and 3) the comparison of simulated and measured signals. Clutter Modeling Surface Clutter Overview. First of all, I am really grateful and thanks to Allah the Al-Mighty who gave me the strength and guided me throughout my PhD journey and my life. Phased Array System Toolbox. The very commonly used and well established base band equivalent model for radar clutter is a complex Gaussian process, which implies that Chi-Square for power, or equivalently Rayleigh for amplitude. Surface clutter refers to reflections of a radar signal from land, sea, or the land-sea interface. The fusionRadarSensor System object™ generates detection or track reports of targets. Surface clutter refers to reflections of a radar signal from land, sea, or the land-sea interface. The resulting system level complexity drives the need for modeling and simulation at all stages of the development cycle. how can we simulate range ambiguous clutter in matlab phased array toolbox ?? Hello…with matlab phased array toolbox, how can we simulate Range ambiguous clutter?? phased.ConstantGammaClutter simulates clutter up to the horizon range. Radar researchers and systems engineers often use tools such as MathWorks MATLAB software and MathWorks Simulink ® software to interactively design waveforms and sensor arrays and to explore various complex trade-offs across the entire multifunction radar system workflow—from RF and antenna components to signal processing algorithms. Examples of traditional radars are scanning radars, which are responsible for searching targets, and tracking radars, which are responsible for tracking targets. Simulate the clutter return from terrain with a gamma value of 0 dB. This example shows how to simulate clutter on a graphical processing unit (GPU) or through code generation (MEX) instead of the MATLAB interpreter.
