Abstract: To provide a measurement data processing device that can improve resolution by applying a correction operation to low-resolution microwave radiometer output data. A measurement data processing device is capable of improving resolution by multiplying a measurement data group of a microwave radiometer by a weighted vector and adding up the measurement data group. The weighted vector solves an inverse problem based on a mathematical model for forming the sensitivity of an antenna as a Gaussian curved surface. Optimization is applied by repeatedly executing, outside an xy coordinate of a target antenna sensitivity distribution function table, a correction operation for minimizing integrated values of a positive remainder sensitivity function, which is data having a positive value a negative remainder sensitivity function, which is data having a negative value.

Abstract: [Object] To provide a wing achieving reduction of friction drag and easy to design and also easy to manufacture and an aircraft including such a wing. [Solving Means] A wing 1 is typically used as a main wing of an aircraft 100. The wing 1 is a swept-back wing having a swept-back angle A. The wing 1 is configured such that a surface pressure (pressure distribution (Cp)) on an upper surface of a vicinity of a leading edge 11 in a fluid increases from a wing root 17 to a wing tip 15. A cross-flow component of an external streamline of a surface of the wing 1 is reduced in the vicinity of the leading edge 11, and boundary layer transition is not easily induced in the vicinity of the leading edge 11. With this, friction drag caused by cross-flow instability can be reduced.
