NASA and ISRO’s NISAR satellite will map Earth’s land and ice in 3D using dual-band radar, detecting movements as small as a centimeter to monitor disasters, land shifts, and climate changes.

An elevation and azimuth direction-finding (DF) method is presented by introducing the pattern reconfigurable antenna (PRA) into a two-element array. An equivalent multidimensional array is built by ...

We present new closed-form and low-complexity solutions for the three-dimensional (3D) target motion analysis problem using azimuth/elevation angles. A 3D pseudolinear estimator (PLE) is developed ...
