AI Technical Summary
Technical Problem
The high sidelobes of the autocorrelation function of the sensed signal lead to severe interference between multiple scattering points on the target during the sensing/imaging of extended targets, affecting the sensing accuracy.
Method used
The sensing signal is generated using a Chebyshev window or a Taylor window. By adjusting the sidelobe level and the main lobe width, the scattering characteristics of the extended target are adapted to improve the sensing accuracy.
Benefits of technology
By flexibly adjusting the sidelobe level and main lobe width of the autocorrelation function of the sensed signal, the sensing accuracy and imaging effect of extended targets are improved.

Abstract
A communication method and device can improve sensing accuracy, especially the sensing accuracy of extended targets. The method comprises: a sending end can determine a third sequence according to a first sequence and a second sequence, and then send a first signal generated according to the third sequence. Wherein, the second sequence is Chebyshev window or Taylor window, and the first signal is used for sensing or communication. The receiving end receives the echo signal of the first signal, and determines the sensing result according to the echo signal and the second sequence. That is, the sensing signal can be generated by using Chebyshev window or Taylor window. Since the maximum side lobe level corresponding to Chebyshev window or Taylor window can be adjusted, there is a corresponding relationship between the side lobe level and the main lobe width, therefore, when the sensing signal is generated based on the second sequence, the side lobe level and the main lobe width of the autocorrelation function of the sensing signal can be flexibly adjusted, so as to adapt to the scattering characteristics of the extended target and improve the sensing accuracy of the extended target.
