With its high-speed digital processing, customizable antenna choices, and built-in Ethernet interface, the design supplies a strong basis for designing radar methods with excessive accuracy and determination.
The MR2001_RD reference design is a vital instrument for design engineers trying to develop high-performance 2D radar transceivers. Constructed round NXP’s MR2001 (‘Spirit’) chipset, this reference design provides a versatile and adaptable radar system with six obtain channels and a low part noise transmitter, making certain exact sign acquisition. It’s notably helpful for engineers engaged on automotive radar, industrial sensing, and superior sign processing purposes.
The frequency sweeps are generated utilizing the CPU’s digital-to-analog converter (D/A converter), permitting correct modulation. The radar system processes goal info from the six obtain antennas, digitizing the indicators and using high-speed digital sign processing to carry out vary and Doppler Quick Fourier Transforms (FFTs) with an replace price of ten measurements per second. The high-frequency bandwidth contributes to wonderful distance decision, making certain exact goal detection. The processed goal info is transmitted by way of the built-in Ethernet interface, enabling environment friendly information communication.
One of many key benefits of this design is its flexibility. Customers can change the antenna and incorporate their very own signal-processing {hardware}, making it adaptable to numerous purposes. The radar system is supplied with an instance MATLAB software program package deal, together with radar firmware written in C-code. This permits customers to customise the system in keeping with their necessities. A graphical consumer interface (GUI) is included, permitting the choice of totally different radar modes and offering a visible illustration of targets in 2D range-Doppler maps or a range-angle show.
The design provides a number of superior options that improve its performance. It operates as a 76–77 GHz radar transceiver with digital sign processing, offering high-resolution goal detection. The system is constructed on NXP’s MR2001/MPC5775 chipset, making certain dependable efficiency. Its open-frame building permits easy accessibility to elements, facilitating modifications and upgrades. Each the antenna PCB and the processing board could be changed, providing flexibility in customization. The design incorporates 4 transmission (TX) channels and 6 reception (RX) channels, enhancing the radar’s capability to detect and observe targets successfully.
Moreover, the system employs an open-loop frequency era mechanism, contributing to secure and exact radar operation. Customers can swap between extensive and slim transmission beams, enabling adaptation to totally different detection eventualities. The built-in Ethernet interface permits seamless information switch and connectivity, making certain clean communication with exterior methods. These options make the design a extremely adaptable and environment friendly resolution for radar-based purposes requiring excessive accuracy and superior sign processing capabilities.
