摘要： In a DME ground apparatus, under the control of a transmission-rate monitoring control unit, the transponder unit decodes an interrogation signal it has received and generates a response signal. The transmission rate at which to transmit the response signal is monitored. If the result of the monitoring indicates that the transmission rate has reached a preset value, the response signal is transmitted from the DME ground apparatus. If the result of the monitoring indicates that the transmission rate has not reached a preset value, squitter pulses are transmitted from the DME ground apparatus.

摘要： A system for the relative navigation of aircraft and spacecraft is disclosed which uses a series of short duration, unmodulated radio pulses transmitted from a phased array antenna. The aircraft or spacecraft whose position is to be determined from another is called as the local station, whereas the other craft with the phased array antenna system is called as the transmitting station. The local station transmits a radio query pulse to the transmitting station. In response to the radio query pulse, the transmitting station transmits a series of unmodulated radio pulses, where each radio pulse is transmitted with a three dimensional radiation pattern that is different than the three dimensional radiation patterns of the other radio pulses transmitted by the transmitting station. A receiver attached to the local station aircraft or spacecraft receives each radio pulse, generates a signal that describes the radio signal strength of the received signal and sends that signal strength number to a stored program processor which stores that signal strength number into memory. After a series of radio signals are received at the local station and at least two radio signal strength measurements are stored in memory, the stored program processor calculates the power ratio or ratios of each received radio signal strength from each radio pulse transmitted by the transmitting location. Bearing is then determined by comparing the calculated radio signal power ratios with a library of angles that correspond to specific power ratios for all radio radiation patterns transmitted. The local station also records the time elapsed from when the first radio pulse is received from the transmitting station after the radio query pulse is sent. Range is determined by dividing that elapsed time by two and multiplying that time with the speed of light.

摘要： A wireless tracking system consists of a wireless target including a wireless communication system for transmitting a data packet over a communication path, and a locating station for determining a position of the target. The data packet transmitted from the target includes an identification code uniquely associated with the target. The locating station includes a configurable directional antenna, a communication interval processing system, a direction processing system, and a position processing system. The communication interval processing system is in communication with the directional antenna and determines the transmission interval of the transmitted data packet over the communication path. The direction processing system determines the transmission angle of the communication path, and is in communication with the directional antenna for controlling the configuration of the directional antenna so as to facilitate the determination of the transmission angle. The position processing system is in communication with the interval processing system and the direction processing system, and determines the target position from the identification code, the transmission interval and the transmission angle.

摘要： Frequency resources of a DME/TACAN band specified for the aircraft band are effectively utilized, and a GPS reinforcing data is overlapped onto distance information to be broadcast. A header is added to a DGPS reinforcing data, and the transmitting pulse level of a conventional ground DME system is modulated, and the data is broadcast to an airborne system. In the airborne system, a threshold value of “1” and “0” is generated by a level detecting device (5), and the start point of the data is detected by a header detecting device (6), and the reinforcing data is supplied to the airborne system. Consequently, the function of broadcasting a data by overlapping the data onto the distance information of the DME is achieved. Since the DME uses the L band, the radio interference with the existing ILS, VOR, aircraft radio transmission, and broadcasting station can be avoided.

摘要： A comparator circuit compares two temporally separated input bursts of signals which occur at two different frequencies. The first burst is an interrogation pulse and the second burst is a reply pulse in a DME system. The comparator circuit includes a first frequency converter (CO1) for receiving at an input thereof the two input bursts, and a comparing device (DC) connected to receive an output of the first frequency converter (CO1). In order to reduce the measurement errors, the first frequency converter (CO1) receives at the input thereof the two input bursts and converts them into two new bursts of signals that have a common frequency so that the comparing device (DC) can carry out the comparison at the common frequency.

摘要： An apparatus to be employed within a precision distance measuring system for estimating pulse time-of-arrival. The apparatus facilitates the use of an Adaptive Fixed Threshold method for such estimation. The invention compensates for pulse time detection errors induced by variations in incident pulse amplitude and shape by adjusting the estimated time-of-arrival. This adjustment is performed as a function of the measured pulse slope between two low-amplitude threshold levels through the use of a predetermined reference table of error adjustment times.

摘要： A two-way ranging system in which deviations of transmit times of interrogation signals from a nominal transit time are determined at a transponder. These deviations are dependent upon the propagation conditions for interrogation and reply signals in the medium of propagation. A normally fixed delay is developed in the transponder. This fixed delay occurs between the reception of an interrogation signal and the transmission of a reply signal. This fixed delay is so shortened as to compensate for transit time deviations of the interrogation and reply signals.

摘要： Apparatus for searching for range indicating pulse signals received as part of distance measuring equipment which first form a list of distance indications in a first search time. The distance indications obtained in a second search time are then logically combined with those indications in the first list and any combination that results in a difference value of less than a prescribed amount is retained for list updating purposes until there is only a single distance indication left in the list. The apparatus can then change to a track mode by placing a search window around the single distance indication thereby reducing the amount of extraneous information to be manipulated by the receiving apparatus.
