摘要： PROBLEM TO BE SOLVED: To control radiation of unnecessary spectrum while stably generating sampling pulses with a high amplitude and a narrow pulse width, to avoid the increase of the cost required for reducing the unnecessary spectrum, and to facilitate the time scanning of sampling timing.SOLUTION: A sampling pulse generator generates impulse-like short pulses required for the transmission or impulse-like short pulses required for sampling of the received wave without using a high-speed switching element, by an equivalent signal processing to orthogonal frequency division multiplexing modulation in a transmission pulse generating section 10 and a sampling pulse generating section 20. Hence, the radiation of unnecessary spectrum is controlled while stably generating sampling pulses with a high amplitude and a narrow pulse width, the increase of the cost required for reducing the unnecessary spectrum is avoided, and the time scanning of sampling timing is facilitated.

摘要： Faraday Rotation causes rotation of the plane of polarisation of plane polarised radiation emitted by a radar e.g. a synthetic aperture radar and, if returns polarised in orthogonal planes are measured at the synthetic aperture radar in order to determine polarimetric characteristics of the ground, which could show up features of the ground such as crop patterns, the measurements made at the SAR are contaminated by the Faraday Rotation. In the invention, the transmitted plane polarised beam is pre-rotated in transmitter 9, the radar returns in receiver 13 are mathematically adjusted in signal formatting 14, 15 to compensate for just the pre-rotated angle, to produce data streams on downlink 16 uncontaminated by the Faraday Rotation. The Faraday Rotation may be estimated by external means 11, 12, or by performing correlation 10 of the orthogonally polarised radar returns to establish a minimum, while the pre-rotation angle and mathematical correction of the returns are being iteratively adjusted, at which Faraday Rotation is assumed to be compensated.
