High resolution, synthetic aperture, side-looking radar system e.g., for satellites, has n-different spatial spectral regions for ground reflected signals with given overlap of azimuth or Doppler spectrums

摘要

Radar system whose antenna beams are directed to ground soil. The distance of n-transmit/receive units are laid out in the flight direction and/or the viewing angle in the n-spread antenna beams, so that n different spectral regions of the signals returned from earth are received with a given overlap. The n-antennas of the n-parallel work operating transmit/receive units are provided with different mutual spaces for moving over the earth surface, and are directed to the ground strip, so that their antenna beams overlap their radar footprints on the ground in the lengthwise (flight) direction.
