# What do you mean by slant range?

## What do you mean by slant range?

In radio electronics, especially radar terminology, slant range is the line-of-sight distance along a slant direction between two points which are not at the same level relative to a specific datum.

What is slant range and ground range?

Imagine the right-angled triangle RNG where R is the Radar, N is Nadir (ground below the radar) and G is the location of your furthest slant range pixel that touches the ground. Then RG is called the Line Of Sight (LOS) of the radar. It is also called slant range. The line NG is called ground range.

### What is slant range resolution?

The minimum distance by which two objects on the ground must be separated in order to be resolved by a radar. The minimum distance must be equal to or greater than half the pulse length of a radar.

How do you calculate DME slant range?

A 1 degree offset angle at 60 nm equates to 1 nm of displacement.

1. Distance off track = (number of degrees off course x distance to station)/60.
2. Maximum drift angle (Max Drift) = Windspeed divided by Groundspeed in miles per minute.
3. Slant Range Overhead DME = Altitude in feet/6000.

#### What do you mean by slant?

1 : to take a diagonal course, direction, or path. 2 : to turn or incline from a right line or a level : slope. transitive verb. 1 : to give an oblique or sloping direction to.

What is the elevation angle?

The elevation angle (used interchangeably with altitude angle) is the angular height of the sun in the sky measured from the horizontal. Confusingly, both altitude and elevation are also used to describe the height in meters above sea level. The elevation angle varies throughout the day.

## What does ground range mean?

ground range In radar terminology, the distance between the nadir and an object. See also RANGE. A Dictionary of Earth Sciences.

What is SLAR used for?

SLAR is an active sensor; the system provides its own source of illumination in the form of microwave energy. Consequently, imagery can be obtained either day or night. Since microwave energy penetrates most clouds, SLAR can be used to prepare image maps of cloud-covered areas.

### What is tacan in aviation?

: a system of navigation that uses ultrahigh frequency signals to determine the distance and bearing of an aircraft from a transmitting station.

What are the components of ILS?

An ILS normally consists of two or three marker beacons, a localizer, and a glide slope to provide vertical and horizontal guidance information. The localizer, operating in the 108–112 MHz band, is normally located 1000 feet beyond the stop end of the runway.

#### What is slant height?

The slant height of an object (such as a frustum, or pyramid) is the distance measured along a lateral face from the base to the apex along the “center” of the face. In other words, it is the altitude of the triangle comprising a lateral face (Kern and Bland 1948, p.

Which is an example of slant?

An example of a slant is an upward slope. An example of a slant is a conservative editorial approach in a newspaper. A slope or incline. The house was built on a bit of a slant and was never quite level.

## Which is the correct definition of the slant range?

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).

What is the meaning of the word Slant?

Here are all the possible meanings and translations of the word slant range. In radio electronics, especially radar terminology, slant range is the line-of-sight distance between two points which are not at the same level relative to a specific datum.

### Is there a slant range to ground range distortion?

Nevertheless, the measurement error is relatively small. The slant range to ground range distortion is much more pronounced in airborne SAR systems. The range between a ground radar and the ground projection of the target is called the Down Range.

Can a 2D radar set make a slant range?

Older 2D radar sets, like the ASR-910 still used in the air traffic management, cannot make this, unfortunately. The operator must know and take into account automatically in his work here that the target of an airplane flying in a larger range is indicated on the scope in an even larger range as really!
