The system also includes an analog to digital converter module for converting each of the analog signals to digital data samples and outputting separate streams of digital data samples corresponding to each of the first and second antenna elements as first and second data streams. An in-phase and quadrature detector module includes a phase shift module for shifting each of the first and second data streams by a predetermined amount of time to form first and second phase shifted data streams. A surveillance module determines a bearing of the target based on in-phase and quadrature data.

摘要： A directional receiver is provided for an aircraft collision avoidance system. The receiver may include input channels that are configured to receive uncompressed linear analog signals from antenna elements that are arranged within a predetermined antenna element geometry. The receiver may further include Analog to Digital (A/D) converter modules, a quadrature converter module and a combiner module. The A/D converter modules can convert each of the analog signals to uncompressed linear digital data and output separate digital data streams that correspond to each of the input channels. The quadrature converter module can mix the digital data streams with corresponding digital reference signals to produce digital In-phase (I) and Quadrature (Q) streams.

摘要： A container for containing an experimental test animal includes a body portion. A neck extends from a first end of the container for connecting the container to a source of gaseous material. An inner surface defines an opening at a second end of the container. An insert is removably retained within the neck, and has passage for fluid communication between the source of gaseous material and the container. A retainer is mounted within the opening of the container, and includes a retainer body and a retainer neck extending from the outer edge of the retainer body. A camming member is pivotally mounted to the retainer neck and is shaped to releasably engaging an outer surface of the container. A mounting ridge is formed in an outer surface of the body portion. The mounting ridge includes a retaining surface for mounting the container with respect to the source of gaseous material.

The system has a phased antenna array comprising antenna elements. The method comprises transmitting a first signal from a first antenna element in the array, and receiving the first signal at a third antenna element. The first signal may represent an interrogation signal transmitted in connection with a surveillance transmit sequence to locate potential intruding aircraft into a range of the protected aircraft. The method further includes transmitting a second signal from a second antenna element and receiving the second signal at the third antenna element. The method also includes calculating calibration information for the antenna array based on the first and second signals received at the third antenna element.
