In a multi-channel Synthetic Aperture Radar (SAR), a SAR group antenna with several receivers is reproduced by means of time-multiplexing a receiver, wherein each receive channel is assigned an antenna segment and, parallel to multiplexing a receiver, a different amplitude allocation is given to the antenna. More "virtual" channels than are physically present are provided, which is achieved by an increased pulse repetition frequency (PRF). The amplitude allocation of the antenna can be assigned during transmission, during receiving and during transmission and receiving. Multiplexing can be advantageously expanded by operating receivers in parallel mode and modifying the so-called "burst-mode technique", which is otherwise used in Scan-SAR systems. Used in multi-channel SAR and SAR interferometry, especially satellite applications.

Phase ambiguities measured in an interferometric microwave radar method are resolved by phase unwrapping in the form of analyzing two interferograms based on different wavelengths, from which a so-called delta k interferogram is obtained having a substantially greater wavelength serving as a value for estimating the absolute phase without further unwrapping. For this purpose, two trains of radar transmission pulses are generated at the transmitter end operated in separate different wavelength ranges and each pulse of which is always emitted simultaneously or sequenced in time in thus forming together a train of two- wavelength pulses. At the receiver end the received signal spectrum is split into two sub-bands each containing one of the two different wavelength ranges, and the interferograms materializing in these two sub-bands are added to result in the delta k interferogram which is then employed as the value for estimating the absolute phase and thus also the absolute distance measured value for the pixels. Applications in generating elevation models and in aerospace sensing object and flow velocities.

In pointing a vehicular (7) mounted directional antenna (5) of a satellite signal receiver at a communications satellite transmitting radio signals by means of analyzing the receiving levels of radio signals transmitted by the satellite and received via the directional antenna, tracking being preceded by a pointing and acquisition mode for initial and repeat pointing of the directional antenna at the satellite, activated as soon as the received signal drops below a defined signal level threshold, signal shadowing caused by obstacles (8) in the link between satellite and directional antenna are sensed by means of a sensor system additionally provided on the vehicle and information as to the shadowing zones in the field of view and/or in the motion range of the directional antenna output and the pointing and acquisition mode is disabled for the duration of passing the shadowing zones on the basis of the information obtained by means of the sensor system as to the shadowing zones following the tracking phase or deactivated following a pointing and acquisition mode, despite the received signal dropping below a defined signal level threshold. For use in mobile satellite communications.

Abrégé

The invention relates to a mobile remote detection device for accumulations of methane, comprising an emitter device having a light source in order to generate light, the wave length of said light source being tuned with the spectral signature of methane, whereby the light can be directed onto a measuring field. Said detection device also comprises a detector device for detecting backscattered light, and an evaluation device. The aim of the invention is to improve said remote detection device in such a manner that it has a high degree of measuring sensitivity with a compact and stabile structure. According to the invention, the light source generates light with a wavelength at which methane is absorbed, wherein the wavelength lies between 3200 nm and 3300 nm and the light source has an optical parametric oscillator with injection seeding, said oscillator being associated with a pump laser which is operated in injection seeding mode.
