Stereoscopic intelligence

Also planned and perspective, also used a stereoscopic shooting. It gives relief and facilitates the detection of camouflaged objects. Stereoscopic photography can be planned and perspective.

The positive properties of the photo-reconnaissance:

a) complete completeness and accuracy;

b) comparison of images of the same object filmed by at different times of the day or during certain periods of time, and the use of various techniques (stereoscopy filters) allows you to open the camouflage enemy activities.

The negative properties of photo-reconnaissance:

a) dependence on the state of the atmosphere and time of day; for example, in the early morning and late evening hours, aerial photography does not give positive results (oblique rays of the sun, haze, insufficient lighting);

b) the duration of photolaboratory, installation and decoding works, which increases depending on the number of photographs;

c) the compulsion of the route and flight altitude when photographing, which increases the danger from anti-aircraft artillery and enemy air fire;

d) in addition, photographic reconnaissance requires more reconnaissance aircraft than visual reconnaissance.

Produced simultaneously with photographing visual intelligence facilitates the interpretation of images and fills gaps and possible failure when photographs.

Photo-reconnaissance is carried out:

a) when it is required to obtain data on important objects in addition to visual observation or to control information obtained by other types of reconnaissance;

b) when reconnaissance objects are replete with details that cannot be fixed during visual observation (fortified

strips, railway stations, and so on. n.);

c) when the object is well camouflaged (location in settlements, artillery positions) and when repeated photographic reconnaissance can establish changes occurring in it (for example, the intensity of defensive work to strengthen the line);

d) when, according to the conditions of the situation, the time allows the use of photographic reconnaissance data.

The greatest development and significance of photographic reconnaissance gets in a trench warfare.

The scale of aerial photographs and their importance for photo-reconnaissance

Visibility of details on the photograph depends on the scale with the king, so the scale of the photograph is selected in strict accordance with the type and purpose of exploration. Fly: a numerical scale and a linear scale shooting.

The scale is dependent on the flight altitude and the focal distance of the machine.

Aerial - this intelligence document that should satisfy all the requirements of completeness of intelligence. Completeness aerial photograph provided by the best one for zoom photography.

The required aerial photograph depends on the completeness ask photographing. If the object of exploration is not yet known, it is required to open. Complex objects with a large number of elements or objects that have a strong air defense, does not allow the visual exploration (defense zones, railways, industrial, administrative and political centers, and so on. M.), Are subject to the continuous photographing. This method of investigation is called photo-reconnaissance.

Fixing any changes occurring in the system of a complex object (which is already known, opened earlier), it is the task of the photographic observations. It is performed by photographing parts of a complex object, the most important or suspicious in relation to masking.

Get detailed information on the individual components of a complex object (a type of artificial barriers, trench profile, type of loopholes in the trenches, the type of flanking buildings, structures character, character masking techniques) achieved the production of photographic research.

In addition to these cases, photography is used:

a) as a means of documentation and clarification of everything discovered by visual reconnaissance;

b) to check data obtained by other types of reconnaissance, both airborne and ground;

c) as a way to control the actions of their troops: artillery, infantry, tanks, aviation, navy;

d) for the purpose of cartography - drawing up new plans, maps, diagrams, correcting or supplementing existing ones.

Pictures can be carried out in the interests of staff and troops {production planned or aerial perspective of individual objects, routes and areas).

To determine the height of photographing at different focal lengths and the "scale and serve tables 19 20, and to select masiggaba - table 21-26.

For the benefit of photographic reconnaissance tanks

For the benefit of photographic reconnaissance tanks should illuminate the area, which will be held on their fighting course.

The scale of photography should be such that the objects (trees, shrubs, potholes, relief and so on. N.) Looked at the aerial photographs as well as they will be visible to the driver of the tank into the slot.

To do this, the angle of the optical axis of the lens to be 5-10 °, and the height of the flight 15-20 / and (at low level flight height). Under such circumstances, the only possibility - it is photographed in a ponytail. Go for photography on the axis of the course of combat tanks should be in the rear.
