摘要： A method for calculating a center frequency and a bandwidth for a radar doppler filter is herein described. The center frequency and bandwidth are calculated to provide radar performance over varying terrain and aircraft altitude, pitch, and roll. The method includes receiving an antenna mounting angle, a slant range, and velocity vectors in body coordinates, calculating a range swath doppler velocity, a track and phase swath bandwidth, and a phase swath doppler velocity. The method continues by calculating a range swath center frequency based on the range swath doppler velocity, calculating a phase swath center frequency based on the phase swath doppler velocity, and calculating a level and verify swath bandwidth based upon the track and phase swath bandwidth.

摘要： In a position detecting system used to monitor a suspicious person and to give an alarm by using a radar which transmits/receives a microwave or a millimeterwave, the shape of a detectable area of the radar and that of the area to be monitored are not always equal to each other, and thus, an alarm may be erroneously given in response to the object outside the area to be monitored. For its solution, the area to be monitored is surrounded by a plurality of reflectors, and the coordinate values of the reflectors and the detecting object are calculated based on the signals reflected from the reflectors and the detecting object and then compared. When the coordinate value of the detecting object is inside the area to be monitored, it is determined that the detecting object is an intruding person or the like and an alarm is given. When the coordinate value of the detecting object is outside the area to be monitored, it is determined that the detecting object is not an intruding person or the like and no alarm is given. In addition, if the calibration and self diagnosis of the radar are periodically performed by using at least one of the reflectors, it is possible to maintain the performance of the radar in an optimal state.

摘要： A method for processing radar return data to determine a physical angle, in aircraft body coordinates to a target, is disclosed. The radar return data includes a phase difference between radar return data received at an ambiguous radar channel and a left radar channel, a phase difference between radar return data received at a right radar channel and an ambiguous radar channel, and a phase difference between radar return data received at a right radar channel and a left radar channel. The method includes adjusting a phase bias for the three phase differences, resolving phase ambiguities between the three phase differences to provide a signal, and filtering the signal to provide a physical angle to the target in aircraft body coordinates.

摘要： An on-vehicle apparatus for recognizing objects is provided. The apparatus comprises a transmission/reception unit, detection unit, estimation unit, and specification unit. The transmission/reception unit transmits a medium wave toward a desired directional range from the vehicle and receives reflected waves of the medium wave and the detection unit detects objects existing in the desired directional range on the basis of the reflected wave. The estimation unit estimates a possibility that each detected object has been detected based on a reflected wave from a first part (e.g., cabin) of a further vehicle other than a second part (e.g., rear part) of the further vehicle, the first part being other than the second part that is the closest in distance to the apparatus-mounted vehicle. The specification unit specifies the second part as an object to finally be recognized of the apparatus-mounted vehicle depending on an estimated result by the estimation unit.

摘要： An interferometric receiver for electromagnetic signals comprises at least two reception channels. Each channel consists of an antenna (A1), followed by a single sideband mixer (M12) and a mixer (M14).As a local signal, the mixer (M14) receives a signal similar to the received signals, taken, for example, from an auxiliary antenna (AR) followed by a limiting amplifier (ALR). The first mixer (M12) receives a frequency from a generator (GFI), which frequency is equal to the value of the intermediate frequency used in the stages (FI1) of this type following the mixer (M14). A phase processing can then be carried out and different countermeasures taken, the simplest of which is a visualization (VI).

摘要： A precision direction finding system for making precision angle of arrival estimates for a signal received through two antenna elements separated in space. Phase interferometry is used to determine a precise angle of arrival, with multiple ambiguities due to the periodic nature of the phase difference related to geometric angle. The interferometric ambiguities are resolved using the time difference of arrival (TDOA) of the signal at the two antenna elements. TDOA is measured using leading edge envelope detection for simple pulsed signals, and predetection correlation for phase and frequency modulated signals.

摘要： Radar emitter carrier frequency or pulse time-of-arrival measurements are used to resolve the differential phase measurement ambiguities on a long baseline interferometer (LBI) used to passively locate the emitter. The LBI requires only two pulses to precisely measure the change in signal angle of arrival caused by observer motion relative to the emitter, whereas frequency Doppler needs tens of pulses, and time Doppler may need hundreds of pulses, to estimate the same change to the same accuracy. Therefore Doppler measurements are made only to the accuracy needed to estimate the angle change accurately enough to differentially resolve the LBI.

摘要： Methods and systems for beamforming are disclosed that include a signal processor that can dynamically determine the relative time delays between a plurality of frequency-dependent signals. The signal processor can adaptively generate a beam signal by aligning the plural frequency-dependent signals according to the relative time delays between the signals. The signal processor can store one frequency-dependent signal as a reference signal and can align the remaining frequency-dependent signals relative to this reference signal. One advantage of the signal processor is that it can align the plural frequency-dependent signals generated by an array of microphones that can be arranged in a linear, two dimensional or three dimensional array and located in a room environment.
