摘要: The invention discloses a system (100) for a fast frequency hopping radio, and comprises a transmit part (110) and a receive part (120). Each of the receive (110) and transmit (120) parts comprise a unit (115, 125) for random frequency generation, the random frequency generating unit of both parts being similar. The random frequency generator (115, 125) of each of said parts comprises a pseudo random number generator, a PRN-generator, the PRN-generator being based on a FIR-algorithm, and said PRN-generator uses a clock signal which has been generated externally to the system as input. The external clock signal which is used is suitably a clock signal from the GPS-system.

摘要: The invention refers to a method and a system for enhancing the measuring accuracy in an antenna array (1), where the method comprises the steps of; a) receiving analog signals on all antenna elements (2) at a first time t1; producing first values for a first radiation diagram from the values in the signals from the first time (t1), and; finding the maximum point (8) for the first values, b)—reducing the signal from one interadjacent antenna element (2) at a second time (t2); receiving analog signals on all antenna elements (2) except from the one switched off or reduced antenna element, and; producing second values for a second radiation diagram from the values in the signals from the second time (t2); c) rejecting all values outside a first range (9) calculated from the first values, and; finding the maximum point (8) for the second values.

摘要: The invention refers to a method for enhancing the ratio between the main lobe (5) and grating lobes (7) in an antenna array (1) comprising a number of n antenna elements (2). The method comprises the steps of; receiving analog signals on a number of m antenna array (1) elements (2); producing a radiation diagram for the array (1) from the values in the signals. The method is characterised in that a number of antenna elements (2′) are switched off or reduced during different times and that the corresponding radiation diagrams for the different times are added to each other such that a sum radiation diagram is produced. The invention also refers to an antenna array system comprising means for performing the method.
