Implementation principle


1. The computer programs to produce specific rules of coded data

2. The data generated by the computer is transmitted to usrp-lw N210 through gigabit network port for further processing: the first line is up conversion, and then the digital signal is converted into analog signal through DAC transformation

3. The daughter board is modulated by analog and then transmitted by the antenna

4. The antenna at the receiving end receives the echo

5. The sub board at the receiving end demodulates the electrical signal: it is sent to the ADC in N210 for analog-to-digital conversion, and then sent to FPGA for digital down conversion, and then the processed data is transmitted to the computer through the network port for further processing

6. The computer compares the data from the receiving end and the transmitting end for analysis and calculation, and presents the information such as the distance and speed of the detected target in a graphical way
