Patent Number Title Of Patent Date Issued
6377905 Method and arrangement for monitoring objects April 23, 2002
The present invention relates to methods and to arrangements for monitoring an object which emits a rotating or oscillating beam whose angular velocity is unknown. The time points at which the beam passes a predetermined number of measuring positions are determined. An angular veloci
6342851 Method and arrangement for duty cycle enlargement January 29, 2002
The duty cycle of a pulse train from a pulse radar antenna is increased by dividing the antenna aperture into sub-apertures (1-5), generating separate pulse trains from said sub-apertures (1-5), and time shifting the separate pulse trains between themselves to produce a resulting pulse
6222487 System and method for measurement April 24, 2001
A method and a system for determining an altitude of an object of interest, for example, an airplane that transmits electromagnetic radiation in the form of radar signals. A number of sub-units that can detect the radar signals are spread out in an area, preferably in a large geographica
6111537 Method for reducing false target echo indications August 29, 2000
Method for reducing false target echo indications in a pulse Doppler radar having at least two different pulse repetition frequencies during the period in which the main beam of the radar illuminates a target. A target which is detected gives rise to a number of primary detections in eac
5990833 System for direction determination November 23, 1999
System for determining the position of radar transmitters where the system includes at least one information center with associated cells and means of communication between the information center and the cells with a restricted transfer rate utilising existing infrastructure in the count
5966091 Procedure and device for the control of a radar unit October 12, 1999
A procedure and a device transmit information in a pulse radar device simultaneously with the ordinary radar function of the pulse radar device. The radar device includes a control unit, a radar transmitter and an antenna. The control unit controls the radar transmitter to generate radar
5920279 Procedure and system for the control of a number of radar units July 6, 1999
A procedure and a system increase the performance of a group of radar units. The radar units are arbitrarily located in such a way that the respective antenna beam of a radar unit functioning as a normal radar at least partially coincides with the antenna beam of at least one other r
5907301 Procedure and device for the control of a radar unit May 25, 1999
A procedure and a device for controlling, in a radar unit for the measurement of target data, the transmission of radar pulses and the reception of target echoes originating from the transmitted radar pulses, in such a way that the performance of the radar unit increases, in order th
