Trombe wall has been invited forty years ago, and lots of researchers involved in studying its diurnal thermal performance in winter. Their terminal object was to improve Trombe wall's thermal performance and popularization by meliorating its structures and materials. But there are little studies about Trombe wall's overheating in summer and overcooling in winter night. In order to popularize the application of Trombe wall, especially use it in the city residential buildings, it must solve the two "over-" problems.

Many new detection techniques are proposed, that include: To overcome the faults of cross-terms and short unambiguity range for the common Wigner-Ville Distribution , short-time Fourier transform and Gabor transform are applied to SAR moving target detection. To improve the detection performance of WVD in noise environment, a new technique based on the Cross-WVD is proposed. The application of fractional Fourier transform to chirp signal detection is analyzed and extended to SAR moving target detection. To eliminate the restriction of chirp-Fourier transform, a new modified definition is proposed and applied to SAR moving target detection. To detect multiple moving targets whose scattering intensities are different heavily, the CLEAN technique is combined with the above techniques and the ideal detection performance is achieved. At last, the whole dissertation is concluded.
