Synthetic aperture radar raw signal generation and image simulation of typical targets

Synthetic aperture radar (SAR) raw signal generation and SAR image simulation of typical targets are very significant for the validation of SAR imaging algorithms, the interpretation of SAR images, and automatic target recognition of SAR images. Based on analysis of the existing SAR raw signal generation and SAR image simulation methods, a new method for SAR raw signal generation and SAR image simulation is proposed. This method combined the curved surface pixel method (CSPM) and the two dimensional FFT (2DFFT) based SAR raw signal generation model. CSPM is used to calculate the target reflectivity, while the 2DFFT method is employed to obtain the raw signal. The simulations are carried out, and the effectiveness of this method is validated by the results of simulating some typical targets.     

Housing Credit and Insurance for Elders

As the new century approaches, the problem of aging society is confronting us. The housing market for elders is becoming a constituent of the housing market in China. It is an indisputable way that credit and insurance play roles in the process of promoting the elder's housing consumption. This paper introduces a different kind of credit-inverse mortgage, suitable for elders, and explores its characteristics and three main forms. For weak abilities of elders to resist risks, this paper also explores some insurance forms that can help elder housing consumers.

This paper presents an algorithm of symbol timing and carrier phase offset acquisition for OQPSK. Proposed algorithm is parallel and has advantages over serial system that recover the carrier phase offset, and then estimate the symbol timing. This algorithm is easy to realize by using digital technology.     

Potential for the Adaptation and the Strategic Implementation of Local and PRC Resources for Industrialised Housing in Chongqing

The provision of quality industrialized housing in Chongqing to meet demand is perceived by the Chongqing Construction Commission to be a key feature of the local construction industry's future development. The growing strategic importance of Chongqing as a developing municipality, at the junction of the Yangtze and Jialing rivers, will ensure continuing economic development in the region. To facilitate such development the local construction industry will need to react accordingly to provide new infrastructure, commercial development, and housing and recreation facilities. Clearly, this must be achieved in accordance with a robust Master Plan, which addresses all issues associated with the built environment and other environmental considerations relating to pollution, conservation and sustainability. Throughout the World it is becoming increasingly recognized that traditional forms of construction are not sustainable in the long term and that new concepts and methods of construction must be developed. Construction must more effectively utilize and re-cycle resources that would otherwise become depleted or exhausted. Further, all aspects of the in-use performance of buildings, especially housing, must be significantly improved. The situation in Chongqing is no exception to this perception and hence the purpose of this paper is to evaluate locally available resources and relevant resources elsewhere in China to assess the potential for adaptation for effective use in industrialized housing. A broad approach will be taken covering all forms of human and non-human resources, especially those resources which can be re-cycled rather than being consigned to waste. By-products from other industries will be considered, such as those from agriculture and manufacturing. A key aspect of this paper is the articulation of a framework to facilitate the realization and development of an industrialized housing system by the creation of an integrated supply chain capable of delivering the necessary design and performance features geared to affordability, conservation and sustainability. The paper will be concludes by presentation of recommendations regarding the introduction of a development strategy geared to an incremental timetable for implementation.     

Problems for Township Construction Teams and Their Countermeasures

Network Structure and Its Strengthening for Fe-C-Si-Mn Alloys

Fe - C - Si - Mn alloys are used as blades in hydroelectric generators contained network structures after some heat treatments. It is found by metalograph and TEM analysis that annealed network structure is pearlite with very fine slice while the normalized is martensite or bainite. Experimental results together with theoretical analysis prove that the network structures are resulted from segregations of carbon and manganese atoms in the interdendritic areas, higher heat treatment temperature or longer soaking time can enlarge the grid size and finally eliminate the network structure. The network structure has some effects on the strength, and the smaller the grid size, the higher the strength.
