<description><![CDATA[Airborne meteorological radars and related networks and models. In one embodiment a network for creating a meteorological model includes a mobile sensing node and a modeling node. The sensing node includes a meteorological RADAR that senses the wind velocity. Data from the meteorological RADAR regarding the wind velocity is received by a processor of the modeling node which determines a model of the wind from the wind velocity. The modeling node combines data from a second sampling node with the data from the first sampling node to create a resultant wind velocity vector. Preferably, the modeling node and the sampling node(s) communicate over an airborne WAN. Another embodiment provides a method of measuring the wind velocity. The method includes steering an RADAR signal out of the plane of travel of the mobile platform. The wind velocity is measured using a return of the RADAR signal.]]></description>

<title><![CDATA[System and method for distributed signal compression for cooperative geolocation]]></title>
<link>http://www.freepatentsonline.com/7365682.html</link>
<description><![CDATA[A cooperative geolocation system and method. The system and method involves time stamping a plurality of received signals and modifying, such as compressing, one or more of the received signals, either with the same or with different rates of compression. A processing subsystem including a geolocation processor is used to correlate various pairs of received signals and to extract time difference of arrival (TDOA) or frequency difference of arrival (FDOA) information and to use this information in cooperatively geolocating the signal source emitting the signals being analyzed. The system enables greater rates of data compression, and thus frees up bandwidth in a network in which it is employed, as compared with previously existing cooperative geolocation systems. The present system further can perform the cooperative geolocation determination without first decompressing the compressed signals, but rather performing a correlation process directly on designated pairs of signals to extract the needed TDOA/FDOA information.]]></description>

<title><![CDATA[FET amplifier, pulse modulation module, and radar device]]></title>
<link>http://www.freepatentsonline.com/7365603.html</link>
<description><![CDATA[An FET amplifier includes an FET for amplifying a high-frequency signal to be input to the gate on the basis of a gate bias voltage from a gate bias control circuit. In the FET amplifier, a high-frequency signal input circuit and the output portion of an inverting amplifier are made conductive to the gate of the FET. A voltage stabilizing circuit generating a positive DC constant-voltage signal is made conductive to the non-inverting input portion of the inverting amplifier, and a gate bias control signal input circuit is made conductive to the inverting input portion through an inverter circuit. When the output voltage from the inverter circuit is 0 V, the inverting amplifier outputs a positive gate bias voltage (in the High state) and, when the output voltage from the inverter circuit is a fixed positive voltage, the inverting amplifier outputs a negative gate bias voltage (in the Low state) lower than the pinch-off voltage of the FET. The FET is ON/OFF controlled by the gate bias voltage and pulse modulates the input high-frequency signal to output the signal.]]></description>

<title><![CDATA[Antenna system]]></title>
<link>http://www.freepatentsonline.com/7365695.html</link>
<description><![CDATA[An antenna system for sharing of operation employs contiguous transmit frequencies. Transmit frequencies are separated into non-contiguous sub-groups isolated from one another by filters  158 (+) and  160 (−) associated with positive and negative polarisation. Received frequencies are filtered and split into five signals for input to base station receive ports. Non-contiguous transmit frequency sub-groups are combined by a quadrature hybrid  110  and pass with 90 degree relative phase shift to mutually orthogonal antenna stack ports P(+) and P(−) associated with orthogonally polarised sets of antenna elements AS(+) and AS(−): the ports P(+) and P(−) are isolated from one another by the hybrid  110 . The 90 degree phase shift results in one transmit subgroup being radiated with left hand circular polarisation and the other transmit subgroup being radiated with right hand circular polarisation. Changing the relative phase shift changes the radiated polarisation to linear or elliptical, and signal amplitude weighting provides control of antenna beam polarisation direction.]]></description>

<description><![CDATA[A radio signal relay device such as satellite is used to cover several relatively small geographical regions with relatively narrow beams as well as a relatively large geographical region with a single beam. This relatively wide beam permits legacy equipment to be used. A transmitting device in a beam transmits a signal to the relay device, which in turn retransmits the signal to a receiving device. The transmitting devices, relay device, and receiving devices synchronize communication by using a particular mode of communication which includes a band of carrier frequencies and a protocol. In addition to communicating like mode signals from a transmitter to a receiver, the relay device may be used in a dual mode communication system to translate signals from the one mode to another. A translator may direct a transmitter to modulate a signal on a different carrier frequency, convert one protocol into another protocol, or both.]]></description>
