A system is for recognizing obstructions and monitoring movements on or above an airport area () with sensors (). A sensor () is a radar device having a plurality of antenna elements (), which are affixed to a curved surface () of an antenna carrier () and are turned on, one after the other, in terms of time. Thus a first part of the antenna elements () is disposed on a first circular line () on the surface of the antenna carrier (), and a second part of the antenna elements () is disposed on a circular line () perpendicular to the first circular line (). Therefore the data of the radar device () are evaluated in a first ROSAR process, to image the situation on the ground, and in a second ROSAR process, to image the heights of the flying objects to be observed.

System for monitoring airport area

A radar system for active obstacle warning and imaging of the surface of the earth, working in the pulse frequency or FH-CW range, which can be used in on-line operation in real time, includes a plurality of antenna elements for sending and receiving radar signals, which are arranged on the fuselage of an aircraft, and which may be turned on and scanned sequentially, whereby a synthetic aperture can be generated by means of periodic sending and receiving of the antenna elements. Antenna elements are arranged along the curved surface of the aircraft contour, whereby a SAR processor is present, which analyzes the data obtained from the antenna elements and displays them as processed radar images on board the aircraft, in a virtual cockpit.

Radar system for obstacle warning and imaging of the surface of the earth

A method for recognizing and identifying objects by means of several sensors, particularly using imaging sensors (L, W, V) in the infrared and/or visible wavelength range and radar devices (R) which are based on the generation of a synthetic aperture. According to the invention, generation of the synthetic aperture occurs in accordance with the ROSAR principle, wherein a plurality of antenna elements (A), which the radar device (R) comprises, is placed on the aircraft (F) along its arched contour (K), controlled sequentially and scanned, and wherein the information acquired by the radar devices (R) and the imaging sensors (L, W, V) is subsequently processed, in such a way that optimal imaging of the surroundings of the aircraft (F) is made possible in every viewing direction.

In a system for supplying power to ROSAR transmitting and receiving antennas that are integrated into the tip of a helicopter rotor blade, wind energy is converted directly into electrical energy locally at the rotor blade tip.

System for supplying power to ROSAR transponders, including transmitting and receiving antennas for ROSAR devices

A ROSAR wire detection method is based upon ROSAR focusing of entire segments of wire. By generating a wire reference signal comprised of a sum of coherent reference signals, the basis for reliable wire detectability is provided.

A device for measuring the speed reached and the distance covered by a moving user or object has a Doppler radar sensor that may be secured to the moving user or object and is made of a microwave strip transmission line sensor ( ) that generates measurement signals and supplies them to an evaluation unit ( ) with a sender that transmits the evaluated data to a separate processing and display unit ( ).

In a method for operating a rotating synthetic aperture radar system that works with pulse frequency or in FM-CW operation in order to detect, penetrate and evaluate objects that are located vertically below the helicopter carrying the ROSAR device, pixels are determined using their own specific doppler histories.

Rosar method for landing helicopters under adverse weather conditions and for recognizing and detecting concealed targets

A method of signal conditioning and processing uses a ROSAR system for obtaining high-resolution elevation data using a fixed transmitting antenna, without requiring a turnstile. A telescope-like extensible transmitting antenna having large vertical dimensions illuminates an area to be imaged in a fanned pattern, creating overlapping elevation sectors. Reflected signals are relayed to a fixed receiving antenna via rotating transponders.

Method of signal treatment and processing using the ROSAR system

A proximity fuse/time fuse, in which the active optical distance sensor switches over to time delay in the case of disturbances occurring at a short distance before meeting the target, such as detonation flash, fog, explosive charge vapor or fireball. The fuse presets the data for the necessary time delay itself from the data of the preceding distance measurements. One exemplary embodiment is described and shown schematically.

Proximity fuse/time fuse for missiles

A device for recognizing useful signals, transmitted over a distance and comprising noisy electromagnetic, light signals containing information. A tapped delay line is used for this purpose, whereby a waveguide is manufactured in a spiral groove of a wafer using microtechnology, in order to form a planar light waveguide coil on a chip.

Opto-electronic correlator including a spiral light waveguide

The present invention relates to a radar system having a synthetic aperture on the basis of rotating antennae. In order to achieve real-time capacity with a high discrimination despite the high data flow, reference functions are determined by a geometry module and a circuit for dividing the strip illuminated by the antennae into a specific number of range intervals. As a result of the division of the overall analysis circuit into individual modules, a complete analysis of the incoming signals can take place despite the high data flow. By signals from additional kinematics sensors integrated into the tips of the rotor carrying the antennae, the reference functions are corrected for rotor movements which deviate from the ideal orbit.

An opto-electronic, interference protected missile tracking system operates according to the multiple shutter shifting method, thereby employing a matrix which may have a plurality of liquid crystal cells or deformable mirror devices. These cells or devices are arranged in a rectangular coordinate system and thus have an inherent location determination so that the need for a mechanically movable reticle is obviated. The individual image points in the matrix are modulated under the control of a location determining central processing unit whereby the individual control covers an 'n.times.m' vicinity around the image point or pixel that is illuminated by the useful incoming light.
