Slant range to ground range conversion
WebMar 15, 2024 · Knowing that a 2 = b 2 + c 2 where a = slant range, b = ground range, c = height. Why can't the DME equipment which calculates the slant range then just convert it to the ground range? Surely for navigation and position fixing knowing the actual ground range would be more useful? Is there a practical reason why the slant range has stuck? avionics WebBased on this, this paper evaluates the performance of range deception jamming on an air-based jammer in a ground-based radar network. In this paper, the ground-based radar coordinate system conversion relationship is first established. Then, the statistical variance data fusion criterion for the radar network is constructed.

WebAs the slant range of the imaging area gets closer, the angle of α under the propagation path and the ground range resolution ρg increases, which leads to a decrease of the ground range resolution, forming the phenomenon of “close range compression” and the geometric distortion of the SAR image. From: Bistatic Synthetic Aperture Radar, 2024 WebLevel-1 Ground Range Detected (GRD) products consist of focused SAR data that has been detected, multi-looked and projected to ground range using an Earth ellipsoid model. ... Ground range coordinates are the slant range coordinates projected onto the ellipsoid of the Earth. Pixel values represent detected magnitude. Phase information is lost ...
Web2. After marking your servomotors, you should pre-position the servomotors so that the left servos are at the furthest counterclockwise position (usually 0 deg) and the right servos are at the furthest clockwise position (usually 180 deg). This way all servos start at the lowered position and have range to lift the arms or kick the legs. Webproducts are situated in slant range geometry. The slant range geometry is the natural radar one and is defined by the line-of-sight distance of the radar system to each reflecting object. The SLC product consists of focused SAR data in zero-Doppler orientation. Furthermore, for geo-referencing orbit and attitude information directly provided 4

This is essentially a slant-range to ground-range conversion that averages adjacent oblong pixels and creates a square pixel from them. As an added benefit, the averaging also smooths the image and reduces some speckling effects.
WebSRTOGR performs a slant range to ground range conversion on the input SAR image, without requiring an elevation image or ground control points. SRTOGR can be used instead of the FLIGHT and STG functions when an elevation model does not exist, or where ground control points are difficult to collect (such as over water).
