1. A synthetic-aperture radar signal processing apparatus comprising:

  • an interference phase processor to calculatea first topographic fringe represented by multiple pixels, representing a relative phase between signals contained in two pixels representing a same scatterer in a first set of two synthetic aperture radar images using the first set of two synthetic aperture radar images generated by two sensors having a first baseline length, anda second topographic fringe represented by multiple pixels, representing a relative phase between signals contained in two pixels representing the same scatterer in a second set of two synthetic aperture radar images using the second set of two synthetic aperture radar images generated by two sensors having a second baseline length; and

    an extraction processor includinga phase calculator to calculate a first specific phase that corresponds to a scatterer at at least one specific height in the first topographic fringe and a second specific phase that corresponds to the scatterer at said at least one specific height in the second topographic fringe, anda pixel extractor to extract a pixel corresponding to said at least one specific height from the first topographic fringe and the second topographic fringe, the pixel having the first specific phase in the first topographic fringe and the second specific phase in the second topographic fringe, the first and second topographic fringes being calculated by the interference phase processor.
