A Pseudo-Code Continuous Wave Measurement Radar Technology Based on Snapshot Algorithm

Pseudo-code continuous wave (CW) signal technology using spread spectrum provides a reliable and effective solution to the needs of applications such as high precision measurement and positioning. The application of snapshot algorithm to pseudo-code CW radar ranging and velocimetry has been proposed for radar ranging and velocimetry. After a brief introduction of the foundation of pseudo-code CW radar ranging and velocimetry, the radar measurement principle and operation mode based on snapshot algorithm are described in detail. The design of the pseudo-code CW algorithm based on snapshot algorithm for ranging and velocimetry is given. Simulation verification and analysis were carried out and the results showed that the ranging accuracy of pseudo-code CW radar based on snapshot algorithm reached the meter level, and the frequency measurement accuracy reached the Hertz level. Results of this paper are of reference significance for the theoretical research and engineering applications of pseudo-code CW measurement radar technology.
