An example of slant range is the distance to an aircraft flying at high altitude with respect to that of the radar antenna. The slant range (1) is the hypotenuse of the triangle represented by the altitude of the aircraft and the distance between the radar antenna and the aircraft's ground track (point (3) on the earth directly below the aircraft).
Slant Range: Distance along the true line of sight True: Angle in earth coordinates with true north as the reference Relative: Angle in deck-plane coordinates using vehicle heading as the reference Rectangular: Cartesian coordinates typically known as X, Y, and Z Spherical: Polar coordinates typically known as range, bearing, and elevation
This means that the rifle sight setting for any range from 0 to 500 meters is available. The sight adjustment procedure can be followed step-by-step. 1. Determine the slant range to the target. Assume that a range finder is available that determines that the target is exactly 300 meters distance. 2. Determine the elevation angle of the target.
Calculations for the "slant range" (range between the antenna's phase center and the point on the ground) are done for every azimuth time using coordinate transformations. Azimuth Compression is done after the previous step. Step 5 and 6 are repeated for every pixel, to cover every pixel, and conduct the procedure on every sub-aperture.
Assuming a single transmitter and several receiver channels, the physical along-track distance between Rx and is given by Δx, while λ represents the carrier wavelength, represents the slant range, and and represent the velocities of the sensor and the beam on ground, respectively.
Range information is functionally identical to the method provided by civilian DME: pairs of 3.5 microsecond (μs) pulses (measured edge-to-edge at 50% modulation strength) from an aircraft are repeated by the station being interrogated, using the round-trip time to calculate slant-range distance.
The slant range distance between the radar and the terrain is the cosecant of the angle between the fuselage and the target, and the energy falls off with the fourth root of that number. Without correction, this produced a display where the ground under the aircraft was very bright on the cathode ray tube display, while the terrain at longer ...
Slant range, in telecommunications, the line-of-sight distance between two points which are not at the same level; Slant drilling (or Directional drilling), the practice of drilling non-vertical wells; Slant height, is the distance from any point on the circle to the apex of a right circular cone
