Slant range

Rs Radar slant range from the satellite to the antenna footprint at range R... 

At maximum range, the slant range becomes tangential to the earth so that the grazing angle ip = 0 and from Fig. 5... 

Similarly maximum slant range at the same height is given by... 

Range Resolution. Let r represent the output pulse length and Tr the pulse repetition interval. Pulses travel along the slant range and interact with the ground through the mainbeam as well as the sidelobes of the antenna array as shown in Fig. 13. 

Each pulse travels along the slant range and hence the slant range that can be recovered unambiguously is of size Thus, slant range resolution is given by... 

Translating to the ground plane, since the pulse wavefront is perpendicular to the slant range direction, we get the range resolution on the ground to be... 

Two air transducers were located on poles, 11 and 31 m from the tank center, slant range, and 7 and 27 m, horizontal range, respectively. Two other air transducers were set at various locations but always in a line-of-...

An interesting analysis was made by Bishop (Ref. 19) for safety evaluations. His analysis took the full slant range and trajectory into account, and was made to estimate the furthest path of the worst fragment from an explosion. His results are shown plotted on Figure 27.19. They are recommended as a conservative safety guide for explosive test ranges. 

TCAS was intended to be an independent backup to the normal Air Traffic Control (ATC) system and the pilot s see and avoid responsibilities. It interrogates air traffic control transponders on aircraft in its vicinity and listens for the transponder replies. By analyzing these rephes with respect to slant range and relative altitude, TCAS determines which aircraft represent potential collision threats and provides appropriate display indications, called advisories, to the flight crew to assure proper... 

TAU In collision avoidance, time-to-go to the closest point of approach (CPA) is more important than distance-to-go to the CPA. Tau is an approximation of the time in seconds to CPA. Tau equals 3600 times the slant range in nmi, divided by the closing speed in knots.

We were eleven and a half miles slant range from the atomic explosion, but the whole airplane cracked and crinkled from the blast. I yelled Flak thinking a heavy gun battery had found us. 

Equaticms 4 and 5 hold assuming flat-roof buildings with rectangular layout and SAR images in slant-range geometry.
