slant range

The line-of-sight distance between two points not at the same elevation.

slant range

i. The line-of-sight distance between two points not at the same altitude or level relative to a specific datum.
ii. The actual distance between a ground-based radar and an airborne target. The range indicated by the radar is the slant range.
iii. The actual distance between an aircraft and a ground radio facility. This distance is more than the horizontal distance. A DME (distance-measuring equipment) indicator shows the slant-range distance. Also called a slant line.

r] is the slant range resolution, B the bandwidth of signal, and c the velocity of light.
Once airspeed and dive angle are under control, my attention is then focused mainly on the slant range, target location, and piper placement end-game.
6) AAI publicizes its POP 300 electro-optical and infrared payload capable of target detection at a slant range of 10 kilometers (km) and target recognition at a slant range of 7 km.
The most common types of measurement range configurations are detailed, including far-field range configurations such as the elevated range, slant range, ground-reflection range and compact range; and near-field ranges such as planar, cylindrical and spherical.
As shown in Figure 3, the slant range to a 3km elevation at 5 degrees elevation is 34.
The HEI will explode and throw significant amounts of shrapnel even when fired from a 5 NM slant range, thus giving A-10 pilots 1,150 grenades that they can deliver with precision--extremely effective on small bodies of enemy troops.
As for above issues, this paper presents an accurate and efficient strip-mode SAR raw data simulator of extended scene included fixed and moving targets, where an general analytical slant range model is proposed and the corresponding point target reference spectrum (PTRS) is derived.
