摘要： An antenna receiver system includes an E-field antenna (120), a first H-field antenna (111), a second H-field antenna (112); three antenna radio frequency paths (301, 302, 303, 306, 307, 308) to amplify, filter, and convert three respective outputs from the three antennas to respective first (371), second (372), and third (373) signals. Filters in the antenna paths simultaneously receive at least two of: eLORAN radio navigation signals from eLORAN ground stations; an EM pulse from lightning; and one of: CW unmodulated signals; ON/OFF modulated signals from a NDB radio navigation ground station; or an AM CW signal received from an AM radio broadcast station. A processor (340) processes the first, second, and third signals and outputs information indicative of two or more of: a geographical latitude and longitude position of the vehicle derived from the eLORAN radio navigation signals; a lightning bearing and a lightning range; and a bearing of the vehicle.

摘要： The location of a vehicle having an assigned serial number is determined at a location remote from the vehicle with a system including a central master station and plural local networks, each having a local master station in a bi-directional communication link with the central master station. Each vehicle includes a receiver for Loran-C emissions, a transmitter for modulating a first carrier having a frequency much higher than the Loran-C emissions with pulses having time positions corresponding with and synchronized with Loran-C pulses as the received Loran-C emissions, and a receiver for a second carrier having a frequency much higher than the Loran-C emissions. The first carrier is modulated by vehicle serial number signals. The carriers are transmitted via radio links between the local master station and vehicle. The local master station responds to the first carrier to detect the time difference between pulses modulating the first carrier to determine vehicle position. A data signal transmitted by the local master station to the central master station indicates the vehicle position and serial number. The central master station responds to the data signal to indicate vehicle location and serial number. The central master station transmits an information signal including a vehicle serial number to the local master stations. The central master station derives a voice signal that is converted to an aural signal at the vehicle with the designated serial number. The vehicle includes a receiver for a locally generated vehicle identification signal vehicle condition sensors. Activation of the transmitter on the vehicle is controlled in response to the receiver for the locally generated coded signal and the sensed vehicle conditions, and in response to the serial number signal originating at the central master station.

摘要： The present invention relates to the field of electromagnetic eavesdropping. The invention relates to a method for passively locating a non-movable transmitter (15) on the ground, implemented by a group of at least one receiving station (10), each of the receiving stations (10) comprising a radar detector and a time reference, all the time references being synchronised with one another, said transmitter (15) transmitting a series of periodic pulses, said method being characterised in that a first estimation of the position of said transmitter (15) is carried out by the Bancroft method using the average arrival times of the pulses transmitted by the transmitter (15) at each station (10) of the group of at least one receiving station (10), the obtained result then being used as the starting point of a maximum likelihood method in order to converge towards the position of said transmitter.

摘要： This disclosure deals with processing radio-frequency navigation signals, particularly Loran-C signals, from crossed loop antennas (H-field antennas) by shifting the signal phase from two loops to be in quadrature with respect to each other and adding them together to achieve omnidirectivity of the antenna pattern during the acquisition mode; using the stronger signal of the two during the cycle selection mode to determine the polarity of the received signals; and calculating the relative bearing angles on transmitting stations to determine, with measured bearing, the orientation of the loop antenna with respect to these stations.
