约束项

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.

具体的研究成果如下：针对常用的Wigner-Ville分布在多目标情况下存在交叉项，并且多普勒不模糊范围小的缺点，提出将短时Fourier变换和Gabor变换应用于SAR运动目标检测，分析了其优势所在；为进一步提高Wigner-Ville分布低信噪比条件下的信号检测能力，提出基于互Wigner-Ville分布的运动目标检测方法；分析了分数阶Fourier变换在线性调频信号检测中的应用，提出基于分数阶Fourier变换的运动目标检测算法；对离散Chirp-Fourier变换的定义进行了修正，提出修正的离散Chirp-Fourier变换，克服了限制其应用的约束条件，并用于SAR运动目标检测当中；强度相差较大的多运动目标检测历来是机载SAR技术的一个重点和难点，我们将CLEAN思想融入上述多种算法当中，良好地解决了该问题。

But, there exists a problem that ignoring to the operator's constraint and supervision in state-owned enterprise at present commonly, to enterprise operator,the achievement is short of perfect effective administration and mechanism, cause state-owned enterprise to be at a standstill , inherent assets running off gravely.

但是，目前国有企业普遍存在忽视对经营者约束、监督的问题，对企业经营者的业绩缺乏完善有效的管理与考核机制，致使国有企业停滞不前，固有资产流失严重。因此，建立体现科学发展观和正确政绩观的鼓励自主创新的国有企业经营者的业绩考核评价体系，是其中一项十分重要而紧迫的任务。

About how to establish and improve the property management system, First, we must find out what's the problems in the current system of certified property manager. Then we should go to the roles acted by the professional managers, create a active atmosphere for those managers, set up a certificating institution, and formulate rights laws and regulations. And more steps should be done to advance and perfect the system of professional manager. As to the most important, it is to standardize the qualification certificate system, to establish the education and training system, and to straighten out the incentive and restriction mechanism.

在探讨如何建立和完善物业管理职业经理人制度时，首先必须分析现有物业管理师制度实施的现状以及其存在的问题；其次要在对职业经理人进行准确定位的基础上，实现营造有利于职业经理人制度的氛围，设立统一的注册认证机构，制定严格的法律法规等三项基础条件，进而从资格认证体系、教育培训体系及激励约束机制等三方面探讨该项制度的进一步推进和完善。
