摘要： A wireless location system is configured to operate in a CDMA-based wireless communication network. In exemplary embodiments, location measuring units (LMUs) can synchronize to sectors of base stations and store sector timing information. In response to a request to geo-locate a mobile device communicating with a sector, sector timing information for the servicing sector is sent to other LMUs and the LMUs can use the sector timing information to detect uplink signals transmitted by the mobile device. The location of the mobile device can then be estimated based on time of arrival measurements made by the LMUs.

摘要： Iterative geolocation of a stationary RF emitter through the use of TDOA may include the use of a single portable geolocation (e.g., TDOA) sensor, a pair of portable geolocation sensors and three of more portable geolocation sensors. Adding portable geolocation sensors to the iterative process reduces the constraints on the signals to be located as well as providing a reduction in the number of iterations required to obtain improved location accuracy.

摘要： A method of operating a circular array antenna, Butler matrix, phase shifters and beam forming network is described including a control circuit or computer algorithm for modifying the phase of the phase shifters, one at a time, and measuring the output power received or transmitted by the circular array antenna to estimate the gradient of the output power. The invention overcomes the problem of nulling out interfering signals by modifying the beam pattern of the antenna in certain directions while maintaining the beam pattern in preferred directions for receiving desired signals.

摘要： An apparatus for limiting the rate at which changes on an input signal are applied to the input of a load device. The input signal is clocked out of a D-type flip-flop which output provides the device actuating signal and is also applied to a means for providing a pulse of determinable duration in response to transitions on the flip-flop output signal. During the occurrence of this pulse, the clock signal to the flip-flop is inhibited, preventing a rapid sequence of transitions on the input signal from causing a correspondingly rapid sequence of load device actuations.

摘要： Transmitters are located with a network of sensors by measuring signal characteristics at multiple known locations and processing these measurements at a central node. The sensors communicate their location to the central node along with measured characteristics of the transmitter's signal, and may be required to synchronize with other sensors. Often, GNSS receivers are utilized to locate and synchronize the sensors. However, the GNSS signals may be attenuated by obstructions. In this case, the sensors determine their location by making ranging measurements with sensors that can receive the GNSS signals. The waveform for the wireless backhaul permits this ranging. Additionally, many sensors can determine their location and time synchronize with the geolocation network through reception of signals from other sensors even if they do not have a direct connection to sensors that know their location and are time synchronized.
摘要翻译： 通过在多个已知位置测量信号特性并在中央节点处处理这些测量，发射器设置有传感器网络。 传感器与发射机信号的测量特性一起将其位置传送到中心节点，并且可能需要与其他传感器同步。 通常，GNSS接收机用于定位和同步传感器。 然而，GNSS信号可能被障碍物衰减。 在这种情况下，传感器通过对能够接收GNSS信号的传感器进行测距测量来确定其位置。 无线回程的波形允许这个范围。 此外，许多传感器可以通过接收来自其他传感器的信号来确定其位置和时间与地理定位网络同步，即使它们没有直接连接到知道其位置并且是时间同步的传感器。
