Abstract Based on two isoperimetric inequalities, it is proposed that the capacitance of an insulated convex conductor is a function of the volume, the surface area, and the surface integral of mean curvature. Then the formula in [1] for computing the capacitance of an insulated conductor of arbitrary shape is greatly improved. Examples show excellent agreement with the existing results. © 1995 John Wiley & Sons, Inc.

Broadband interference suppression in DSSS system using fractional Fourier transform

Lin Qi Ran Tao Siyong Zhou

This paper proposes a linear FM interference rejection method in direct sequence spectrum spread (DSSS) communication system based on signal synthesis using fractional Fourier transform. The detection and parameter estimation of the interference signal are implemented in fractional Fourier domain and the synthesized estimate of jamming signal is then subtracted from the received signal, the interference immunity of the system can thus be improved. Performance analysis and simulation results showed that, the proposed method works effectively in a wide dynamic range of SNR, and also, it is easy in computation and simple in implementation.

Study of detection performance of passive bistatic radars based on FM broadcast

Journal of Systems Engineering and Electronics (2007)

Tao Shan Ran Tao Yue Wang Siyong Zhou

The passive bistatic radar based on the FM broadcast has inherent superiority with respect to its survivability. In this article, the ambiguity function (AF) and the cross ambiguity function (CAF) of the FM radio signal are analyzed and illustrated. The Kolmogorov Smirnov (K-S) test verifies that the amplitude probability density function of the CAF side lobes is exponential; the distribution of the target is also deduced. Finally, the detection performance of the passive radar is studied, and the result shows that this new type bistatic radar has favorable detection capability.

A novel method of signal processing for VSAR system

Juan Shao Ran Tao Siyong Zhou Yue‐Sheng Wang

To improve the low velocity resolution of a VSAR (velocity SAR) system and detect slowly moving targets with a VSAR system, modern spectral estimation in the signal processing of the VSAR system is used instead of the conventional DFT (discrete Fourier transform) method. Using modern spectral estimation one can achieve higher velocity resolution than with the conventional spectral estimation. It can decrease the number of antennas and the total length of the array, and improve the azimuth resolution.
