![]() The following figure shows the transmitter subsystem. However, similar to the first example, the transmitter and receiver subsystems are now built with RF Blockset blocks. Once executed, the model shows the estimated range and speed values that matches the distance and relative speed of the target car. ![]() At the top level, the model is similar to what gets built from Phased Array System Toolbox. However, this model uses a triangle sweep waveform instead so the system can estimate range and speed simultaneously. The second example is adapted from Automotive Adaptive Cruise Control Using FMCW and MFSK Technology (Radar Toolbox). This gives the engineer some knowledge regarding the system's performance under different situations. If one sets the IP3 of the transmitter to 70 dB and runs the simulation again, the peak corresponding to the target is no longer as dominant. In real applications, the amplifier will suffer many nonlinearities. For example, the simulation result shown above assumes a perfect power amplifier. With these changes, the model is capable of simulating RF behaviors. From the diagram itself, the model below looks identical to the model shown in that example. With RF Toolbox you can build networks of RF components such as filters, transmission lines, amplifiers. You can use RF Toolbox for wireless communications, radar, and signal integrity projects. The first model is adapted from example Simulating Test Signals for a Radar Receiver in Simulink which simulates a monostatic pulse radar with one target. RF Toolbox provides functions, objects, and apps for designing, modeling, analyzing, and visualizing networks of radio frequency (RF) components. The following sections show two examples of incorporating RF Blockset modeling capability in radar systems built with Phased Array System Toolbox. One advantage of modeling the system in Simulink is the capability of performing multidomain simulations. A popular candidate for such a component is the RF front end. In many cases, once the system model is built, the next step could be adding more fidelity in different components. References 1 Besser, Les, and Rowan Gilmore. The filter design is based on a three-pole Chebyshev highpass prototype with 0.1 dB passband ripple and a cutoff frequency of 1.5 GHz. Several examples, such as Simulating Test Signals for a Radar Receiver in Simulink and Automotive Adaptive Cruise Control Using FMCW and MFSK Technology (Radar Toolbox) have shown that one can build end-to-end radar systems in Simulink using Phased Array System Toolbox™. Design and Analyze HighPass Filter Using pcbComponent (RF PCB Toolbox) This example shows how to design and analyze a microstrip highpass filter.
