摘要： A multi-path resistant frequency-hopped spread spectrum mobile vehicle or personal location system is described which provides low cost manufacture and low power operation while still enabling the accurate location of the mobile unit over long distances and in moderate to severe multi-path conditions. The frequency-hopped spread spectrum mobile vehicle or personal location system consists of a central station, a plurality of base stations and a plurality of mobile transmitters which transmit using a frequency-hopped spread-spectrum differential bi-phase shift keying communication signal. Frequency Shift Keying modulation may also be used. Each of the plurality of base stations include an array of receiving dipole antennas and employs special algorithms for retrieving very low power frequency-hopped spread spectrum signals in a noisy and multi-path environment. The base stations use computational algorithms for determining the phase difference between each of receiving dipole antennas to determine the direction of the transmitter relative to the location of the respective base station. The multiple direction of arrival angles of the received signal at each base station are corrected based on an n-dimensional ambiguity space to locate most probable angles of arrival. The ambiguity space plot is used to eliminate erroneous comparisons of dissimilar phases of the incoming signal. The most probable values are then tracked over multiple frequency hops and a histogram analysis of the strongest surviving angles of arrival is performed. The two peaks of the histogram are used as the two most probable directions of arrival. Each base station then communicates the two relative directions of the transmitter to a central station where the location of the transmitter is determined by triangulation. The direction of arrival angles from the multiple base stations are summed in a least mean square approach to find a single direction of arrival which is then plotted on a gnomonic projection to correct for the curvature of the earth.

摘要： The present invention is an improved direction finding (DF) processing system using digitally implemented spectral analysis. Both phase and amplitude responses are calibrated by comparing each spectrum "bin", or portion of the frequency bandwidth, to the other receiver or receivers output. A random noise source is used, with a large number of noise waveforms being measured and averaged. The average responses are then compared. The difference for each spectrum bin is stored in a passband calibration table. When the direction of origin of a signal of interest is later calculated using the difference in spectra for each bin, the value in the calibration table is first subtracted out.

摘要： A television tracking symbol generator for use in a non-imaging seeker to ovide basic flight test performance that can be instantly understood by watching a conventional television real time display of the airborne TV monitor or subsequent display by means of a video tape recording made during the test. The display contains the dynamic and pictorial rendition of the target movement, the terrain, the weather conditions, the seeker's aim point, the stabilized platform's aim point and the target's signal strength as received at the seeker. All the key performance data about the seeker are integrated and correlated in the TV picture.

摘要： Example techniques relate to playback based on acoustic signals in a system including a first network device and a second network device. A first network device may detect a presence of a user using a camera and/or infrared sensors. The first network device sends, in response to detecting the presence of the user, a particular signal via the first network interface. The second network device receives data corresponding to the particular signal and plays back an audio output corresponding to the particular signal.
