DE2349807A1 - Electronic evaluation for opto-electronic antenna array - uses division of horizontal and vertical planes in identical, different-phase sections - Google Patents

Abstract

The electronic evaluation concerns an antenna array for laser beams and beams with similar propagation characteristics, as in 2310515, to provide spatial direction location for such beams, for reflected and foreign pulses, and for transponder pulse trains. The outputs of all optical or opto-electronic antennae within a spatial angle section in horizontal and vertical direction are associated with a single receiver, after modulation and mutual phase shifting, so as to allocate a give phase lock to each spatial angle section for recognition purposes. This is followed by amplitude selection and electronic adding of two such sections following each other.

Title: Electronic evaluation for optoelectronic antenna system for laser beams and beams with similar propagation conditions (P 23 10 515.9)

The invention relates to a method and a basic circuit used to carry it out.

The invention is based on the object of a method to apply the spatial directional location of Läse, rays and rays with similar propagation conditions, reflected impulses, foreign impulses, as well as Pulse series from transponders with the help of an electronic evaluation (main patent P 23 10 515 »9 Item 6).

The object is achieved according to the invention in that the outputs are all within a rough angle component of ^ f degrees in the horizontal and vertical directions, 3 ^ Lg'.5 ', Fig. 5- and 6, arranged optical bsv / .optoelectronic antennas a common receiver 5 assigned.

These antenna outputs are modulated and in their Phase positions are shifted from one another in such a way that each solid angle component has a specific phase position for the purpose of identification assigned.

By a subsequent amplitude selection according to amount and phase and subsequent electronic addition of two adjacent-selected-solid angle components the resulting phase position is formed according to amount and direction and from the display devices 7a and 7b shown.

This allows a solid angle with a sole and also fixed antenna system determine. · '·

The optoelectronic antenna system is electronic in n ^^ degrees equal sections-divided into horizontal and vertical planes. (with hemispherical shape: η <^ 4 for the vertical plane) 4 shows the basic circuit diagram: All within one solid angle portion of ^ f degrees in the horizontal and vertical planes on the Surface distributed optical or optoelectronic antennas are assigned to a common recipient (common recipient: 5) The output of the receiver (5) is on the amplifier 6.1 (Fig. 4) The output signal from (6.1) is switched in the pulse regenerator (6.2) processes and controls the from the oscillator and frequency multiplier (6. 6) via the phase encoder (6.7) to the control stage (6.3) This voltage is generated in n-different phase positions, each with a 360 / n degree difference, the

The output of (6.3) is fed to the amplitude selector (6.4), and the two largest amplitudes on the input of the addition stage The inputs of the amplitude selector (6.4) are multiple occupied by several solid angle components of the horizontal plane, which all have the common angle of the vertical plane. In (6.5), the two components supplied - die - are always in order the angle ^ are shifted from one another in the phases - the Resultant formed, which is fed to the horizontal display device (7a) and is represented in the correct phase by this Phase position shows "the horizontal reception direction (Az iraut) The display devices 7a and 7b are only required once per system, (drawn several times in Fig. 4)

Vertically adjacent solid angle components of the surface, e.g. (a) and (b) in. Fig.5, Fig.5, above, are combined from the two largest amplitudes of two neighboring areas. The sizes of these two areas are proportional to the receiver Sircc; in branch (a) and (b) the resultant is formed from these again

The resulting phase position of the vertical plane establishes the display device (7b) represents the vertical reception direction. The cross connections between (6.4) and (6.8) are used for control for blocking, switching and assigning inputs to neighboring ones Addition Levels (6.5)

The outputs of (6,5) marked in Fig. 4 with the sign 1) become switched to the third vertical plane (c) selected according to the example and to the input of the phase encoder for the vertical The amplitude selector (6.9) switches the two largest amplitudes to the addition stage (6.91). At the output from (6.9i) the resulting amplitude is available with that of the phase position, that of the vertical reception direction corresponds, and represented accordingly by the display device (7b) will. »·
