Abstract: Embodiments of the invention are directed to improving the sensitivity in polarimetric radar data. In particular, embodiments of the invention improve the sensitivity of such systems with improved post processing techniques. The sensitivity can be improved by using the co-polar elements (off diagonal elements) of the covariance matrix in power and/or reflectivity determinations. This can not only improve the sensitivity but may also enhance identification and improve quantitative estimates of precipitation.

Abstract: The present invention relates to a method and apparatus for simultaneous transmission of horizontal (H) and vertical (V) channels in a dual polarized weather radar. The goal of the invention is accomplished by placing the receiver, duplexer and polarizer equipment above the azimuth rotary joint but below elevation rotary joints. The elevation rotary joints and other associated signal paths are calibrated by using a low power signal on the radar's operating frequency that is fed into couplers above the elevation rotary joints.

Abstract: This publication discloses an apparatus and method for measuring a gas content. The apparatus includes a light transmitter (1), by means of which coherent light can be sent to the measurement object (3), a receiver (2), by means of which light that has passed through the measurement object (3) can be detected, and optical means (4, 5, 6), by means of which the light intensity of the light transmitter (1) can be aimed at the receiver (2). According to the invention, the optical means include a lens element (4), the optical axis of which is arranged essentially obliquely relative to the longitudinal axis of the measurement object (3), so that the angles of the normals of the optical boundaries relative to the measuring signal are set obliquely. The lens element (4) is both a refracting and a reflecting element, and separates the measurement object (3) from the means (1, 2, 5).
