    • An image restoration device according to the present invention includes: a point spread function storage unit which stores any two PSFs among a first range PSF for restoring a first sweep image serving as a sweep image when a sweep range is a first range; a second range PSF for restoring a second sweep image serving as the sweep image when the sweep range is a second range which excludes the first range; a third range PSF for restoring a third sweep image serving as the sweep image when the sweep range is a third range obtained by combining the first range and the second range; and a PSF calculation unit which performs addition or subtraction on the two PSFs to calculate a remaining one among the first, second, and third range PSFs.

    • In a method for measuring a radiation power, an elliptical mirror is prepared so as to have a elliptical spherical space enclosed by a metal wall surface, the space having a rotating axis passing through two focal points. A device under test is placed in a position of one of the two focal points such that a center of radiation of a radio wave substantially coincides with the focal point, and a receiving antenna is placed in an position of an other one of the two focal points. The device under test is caused to radiate a radio wave and the radiated radio wave is reflected at the wall surface to allow the receiving antenna to receive the radio wave. Then, total radiation power of the radio wave is measured at a measurement end of the receiving antenna in accordance with an output signal from the receiving antenna.
    • 在用于测量辐射功率的方法中,准备椭圆镜以具有由金属壁表面包围的椭圆球形空间,该空间具有穿过两个焦点的旋转轴。 被测设备被放置在两个焦点之一的位置,使得无线电波的辐射中心基本上与焦点一致,并且接收天线被放置在两个焦点中另一个的位置 积分 被测设备被辐射无线电波,并且辐射的无线电波在壁面反射以允许接收天线接收无线电波。 然后,根据来自接收天线的输出信号,在接收天线的测量端测量无线电波的总辐射功率。

    • A signal generating section generates a main signal and a noise reference signal. A determining section determines whether a level ratio is larger than a predetermined value. An adaptive filter section generates a signal indicative of a signal component of a target sound included in the noise reference signal generated by the signal generating section, and learns a filter coefficient only when the determining section determines that the level ratio is larger than the predetermined value. A subtracting section subtracts the signal generated by the adaptive filter section from the noise reference signal. A noise suppressing section suppresses a signal component of noise included in the main signal by using the main signal and the noise reference signal after subtraction by the subtracting section.
    • 信号产生部分产生主信号和噪声参考信号。 确定部分确定电平比是否大于预定值。 自适应滤波器部分产生指示由信号产生部分生成的噪声参考信号中包括的目标声音的信号分量的信号,并且仅在确定部分确定电平比大于预定值时才学习滤波器系数 。 减法部从噪声参考信号中减去由自适应滤波器部分产生的信号。 噪声抑制部分通过减法部分减去后的主信号和噪声参考信号来抑制包含在主信号中的噪声的信号分量。
