摘要： Two SODAR systems (12a and 12r) for detecting and characterizing vortices (16) shed from landing or departing aircraft (14) at an airport (10) are positioned so that one, the active system (1 2a) is located beneath likely vortices (16) and the other, the reference system (12r) is located away from the vortices but in the same ambient environment. Thus, where a wind duct or thermal inversion (18) is present, both SODAR systems will detect echoes (22 and 28) generated thereby, whereas only the active system (12a) will detect echoes (24) from wake vortices (16). By differencing the outputs of the reference and active systems, better vortex identification and discrimination is achieved. Only one SODAR system need be used where there sufficiently normal conditions prevail between aircraft activity, since readings taken in the absence of aircraft can be used as reference data for subtraction from 'active' data recorded during the presence of an aircraft.

摘要： A method of determining the latency of a route in a packet-switched network, a packet switch for use in such a method and network and a packet-switched network are disclosed. Preferably, each switch maintains a routing table that records the latency of the routes accessible by that switch. Each switch also preferably has a GPS-based universal time clock which it employs to time the transmission and arrival of identifiable timing packets, these times being used to compute route latency and to up-date the routing tables. In one example (Figure 1) a packet-switched network has a plurality of switches (S1-S6) interconnected by links or trunks (T1-T7). A local GPS-base clock (GPS CLK) is connected to each switch (S1-S6) to enable the accurate timing of transmission and reception of identifiable timing packets in accordance with a system-wide universal timing standard.

摘要： Sodar systems and methods for acoustically sounding air are disclosed in which chirps longer than 300 ms - and preferably with durations of tens of seconds - are used along with matched filter and/or Fourier processing methods to derive phase signals indicative of air characteristics in range. A listen-while-transmit strategy is preferred, the direct signal being removed by subtracting the phase signals from two or more receivers located near the transmitter so as to be in the same noise environment. The resultant differential signals can be related to cross-range wind with range distance. In one example, apparatus (100) is employed comprising a reflector dish (102) over which one central loudspeaker 110 and four microphones (112, 114, 130 and 132) are mounted, the microphones preferably being located on cardinal compass points and having their axes (124, 126) slightly angled with respect to the vertical transmission axis (122).

摘要： A monostatic sodar system using long chirps and send-while-listening techniques employs transmitter-receiver pairs (Tw, Rw; Tv, Rv; Te, Re) that have coincident main lobes (Twm, Rwm; Tvm, Rvm; Tern, Rem). The system uses digital time domain matched filters and frequency modulated or digitally modulated ( eg , BPSK) chirps. Digital frequency domain matched filtering may also be used. The matched filters generate sample streams indicative of the phase and amplitude of echo signals returned from the atmosphere after the transmission of a chirp into the atmosphere.

摘要： A marine sodar system (10) is provided for use on board ship to determine the presence or absence of an evaporative duct in the vicinity of the ship. In one form the system comprises port and starboard transmitters (12p and 12s) and respectively associated port and starboard receivers (14p and 14s) mounted on the mast (16) of a ship (18). Transmitters (12p and 12s) generate pulsed acoustic beams (2Op and 20s) which are narrow in elevation and wide in azimuth while receivers (14p and 14s) have antenna lobes (22p and 22s) that are wide in elevation and narrow in azimuth. Thus, starboard transmitter (12s) illuminates an elongate strip (24s) of the sea surface extending in parallel spaced relation to ship (18) while receiver (14s) interrogates an elongate strip (26s) of the sea surface extending outward orthogonal to the ship. Strips (24s) and (26s) overlap only in a relatively small area (28s) so that echoes of the transmitted signal arising from this area are selectively detected by receiver (14s). The same situation exists on the port side of the ship (18). Returned echoes are processed by the receivers to determine the presence or absence of the duct. Other embodiments are described and the invention is concerned with marine sodar apparatus, marine sodar systems and with shipboard sodar methods of detecting evaporative ducts while at sea.

摘要： A method and system for acoustically sounding the lower atmosphere involves the transmitting of an acoustic chirp and the processing of returned echoes and interference using wavelet and matched filter techniques. A single transmitter and four receivers may be used, with receivers located equidistant from the transmitter on the cardinal points of the compass. N, S, E, & W inputs are digitized and input to a wavelet filter (50) together with the transmitter chirp signal (R or D) for the attenuation of the direct signal and ambient noise signals. The interference-attenuated signals are then processed in a matched filter (52) to extract phase and amplitude outputs (54 and 56), the phase output being unwrapped (70). The N and S phase signals and the E and W phase signals are then separately differenced (74 and 80) and the results used to compute (86 and 92) wind speed and bearing. Extracted amplitude signals (56) are put through a second wavelet filter (58) to remove echo clutter before being stored, along with the wind speed and bearing data in a range gate (96).

摘要： A monostatic sodar system (10) for atmospheric sounding consists of a processor and display unit (12) that generates a set of acoustic chirps for transmission by transmitter 20. Discontinuities (22, 24 and 26) result in echoes (28, 30 and 32) being returned to a receiver (38) of system (10). Receiver (38) outputs extracted echo signals on line to the processor (12) for analysis. Detector (36) implements a Fourier domain matched-filter to extract echo signals from noise. By using a set of multiple chirps of increasing length with increasing intervals between them, substantially any feasible range can be accommodated using send-then-listen techniques with the benefit of high s/n performance.

摘要： A bi-static sodar system and method are used to measure and monitor the wake vortices of aircraft in the flight path of an airport runway. A loudspeaker (16) is arranged on one side of the flight path (12) and transmits a series of acoustic pulses to illuminate portion of the flight path. Multiple microphones (18, 20 and 22) are arranged on the opposite side of the flight path (12) so as to receive direct signals from the loudspeaker (16) and forward-scattered echo signals from an echo source (26) within the illuminated portion of the flight path. The microphones (18, 20 and 22) are arranged at different distances from the loudspeaker so that the time intervals between the receipt of the direct and echo signals from each pulse will vary because of the different locations of the microphones. This variation is used to assist in identifying the location and other characteristics of the echo signals and in generating an output indicative of a wake vortex (28).
