A novel Bar TSV(B-TSV) structure, formed by two semi-cylinders combining with a quadrangular is studied in this paper. This B-TSV structure extends the TSV design options by introducing new design parameters. The scalable electrical model of B-TSV is proposed and the effects of design parameters, such as the side length of quadrangular and the minimum distance between TSVs are investigated and concluded by a 3D electromagnetic solver. Performance comparison between B-TSV and the traditional cylindrical one is also provided by simulation under the Ground-Signal-Ground configuration. Simulation results show that B-TSV has better performance than the traditional one, and can be used to increase the TSV array density without degrading the electrical performance of TSV system.

The target detection feasibility and performance based on the TF energy integration are analyzed in this paper. Assuming the phase of signal is known, the time-frequency(TF) energy signal is got through TF transform, and the energy along the instantaneous frequency(IF) curve is integrated, the TF energy is used for target detection. Analytical and experimental results show that TF energy integration method based the target detection performance increases almost 6dB as compared to non-coherent integration, the advantage of the TF energy integration detection is that the echo signal parameters aren’t needed to be known.
