Title: Radar method for the classification of helicopters
Inventor: FOELLER GERHARD DIPL ING
IPC: G01S13/56
Filed: 1987-11-26
Abstract: In a radar receiver having I/Q channels, helicopters which are detected are classified on the basis of having an odd or even number of rotor blades, by reference to the signal response of the echo signals in the I-channel and Q-channel. A rotor having an even number of blades produces identical signals in the I-channel and Q-channel, which produces in a Gaussian I/Q plane a signal track which moves essentially on a straight line, that is to say is one-dimensional, while in contrast a rotor having an odd number of blades produces non-identical signals in the I-channel and Q-channel, which, in the Gaussian I/Q plane, produces a signal track which covers a surface, that is to say is two-dimensional. The method according to the invention is suitable for use in radar systems having a helicopter sensor. <IMAGE>

Patent DE-3809972-A1 (DE)
Title: Method for transmitting information signals between modules, especially between plug-in modules of a communications system
Inventor: MASANOW MICHAEL
IPC: H04B10/80
Filed: 1988-03-24
Abstract: The information signals between modules whose support plates (boards) are mechanically connected to each other and are arranged essentially parallel to each other are transmitted by means of an optical transmission unit. Its light-emitting transmitter, fitted on the one support plate, is controlled by means of the information signals (radio-frequency clock signals, PCM signals). The emitted light signals arrive at a receiver which is fitted on the other support plate and is aligned in the direction of the transmitter. This receiver is then an opto-electronic transducer which on the output side supplies the information signals again in the original form of electrical signals. When compared to the otherwise conventional transmission of the signals by means of a plug connection between the support plates, this method results in a reduction in the interference radiation and the digital information signals no longer need to be attenuated. Furthermore, no screening measures are necessary and interference signals are prevented from being injected (coupled in). The propagation times are determined only by the optical transmission and no longer depend on the routing of the conductor tracks. <IMAGE>
