New methods of acoustic imaging are presented that provide images with reduced reverberation noise and images of nonlinear scattering and propagation parameters of the object, and estimation methods of corrections for wave front aberrations produced by spatial variations in the acoustic propagation velocity. The methods find use in a variety of applications such as acoustic imaging of geological structures, SONAR imaging of sub-sea objects, and medical ultrasound imaging. The methods are based on processing of the received signal from transmitted dual frequency band acoustic pulse complexes with overlapping high and low frequency pulses. The high frequency pulse is used for the image reconstruction and the low frequency pulse is used to manipulate the nonlinear scattering and/or propagation properties of the high frequency pulse.  3, record 2, English, - acoustic%20imaging

The signal data in the Kobe image was corrupted by a ground-based radar operating in the same frequency band as the JERS-1 sensor. This radar interference caused the streaks of noise that cover the image of the land mass. Other problems that arose in some of the data were the appearance of "ghost images" in the scenes and poor matching between the images.  3, record 3, English, - radar%20interference

Theoretical studies have shown the potential scientific value of multi-spacecraft radio tomographic imaging of the magnetosphere. The <10 RE WIND perigee passes during August 2000 afforded a unique opportunity to test and verify the capabilities of radio tomography by measuring interspacecraft electromagnetic wave propagation parameters using the Radio Plasma Imager(RPI) on IMAGE as the transmitter and the WAVES instrument on WIND as the receiver.... We show how changes in the path-integrated electron density/magnetic field product can be unambiguously measured from this continuous, low signal to noise ratio, single frequency measurement.  2, record 4, English, - single%20frequency%20measurement
