Radar imaging of Mercury's north polar region was done using the Arecibo Observatory's 70-centimeter wavelength radar system during the inferior conjunction of July 1999. We have clearly detected the highly reflective region at Mercury's north pole first identified in radar images at the shorter ...

In a recent paper [1] a model for radar images was derived and a method for mean-square error (MSE) filtering of noisy radar images was presented. The purpose of this correspondence is to point out that the filter in [1] is not optimum in the MSE sense and to show that the ultimate...
The Simple Rectification to Cartesian Space of Folded Radial Velocities from Doppler Radar Sampling Periodic sampling of the Doppler radar return signal at the pulse repetition frequency causes measured velocities to be ambiguous (folded) when true meteorological velocities along the radial direction exceed...

The first category of conditioning methods refers to the echoes acquisition, meaning the acquisition of depth, of the across and along-track distance, of the received beam angle, of the numbers of the transmitted and received beam, or of the two-way travel time of the acoustic pulse. The ...

A side looking radar has a clutter spectrum dependent on the beam-width of the antenna and the velocity of the platform [3]. Typically the pulse repetition frequency in SAR is set to just adequately sample the Doppler spectrum of the clutter. Fast moving targets can have Doppler signatures ...
