摘要： Disclosed is a method for estimating the range to an object, the method comprising: transmitting a first signal towards the object; receiving a reflected echo signal reflected from the object; and determining a measured point (MP) in an N-dimensional phase space. The range to the object is estimated by selecting a candidate range estimate from a plurality of candidate range estimates, each candidate range estimate in the unambiguous range R having an unique associated point in the N-dimensional phase space positioned on range lines, and wherein a candidate range estimate is selected dependent on the distance from its unique associated point in the N-dimensional phase space to the measured point (MP), so that a single range estimate is generated using information from at least two measured phase differences without directly averaging ambiguous range estimates.

摘要： In a dual-frequency CW radar apparatus, first/second beat signals that include reflection components of radar waves conforming to transmission signals of first/second frequencies are generated for each antenna element and the generated signals are Fourier transformed. A power spectrum average of the beat signals is used as a basis for the detection of a peak frequency fp corresponding to the frequency of the reflection components. A second eigenvalue λ2 of a correlation matrix: Ry=(½)·[y1,y2][y1,y2]H is calculated, the matrix being based on first received vector y1/second received vector y2 having elements that are Fourier transformed values of the peak frequency fp. Based on the magnitude of the eigenvalue λ2, whether or not the reflection components corresponding to the peak frequency fp are synthetic components of the reflected waves from a plurality of targets is decided.

摘要： A method for detecting an intruder in a protected space that uses a microwave frequency sensor to determine an accurate distance measurement to the intruder. The accurate distance measurement reduces the false alarms typically associated with microwave frequency sensors due to motion outside the protected space and vibration within the protected space. The motion detector transmits three microwave frequency signals of different frequencies in order to eliminate an ambiguity problem when determining the accurate distance measurement. The accuracy of the intruder distance measurement may be determined with greater resolution by reiteratively transmitting and evaluating microwave frequency signals of different frequencies. The motion detector of the present invention may include a PIR sensor. The accurate distance measurement allows the motion detector to precisely set signal threshold levels for the microwave frequency detector and the passive infrared detector to reliably detect an intruder while discriminating against an animal or other moving object.

摘要： A transmission controller 7B is configured to transmit an R/W request signal for requesting transmission of a tag response signal to a RFID tag 1 twice. At this time, a frequency controller 7A controls a PLL section 5A to transmit the R/W request signal via different carrier frequencies. A phase information acquirer 8A detects a phase change amount of the tag response signal that is transmitted via different carrier frequencies. A distance calculator 8B calculates the distance between the reader/writer 2 and the RFID tag 1 on the basis of the phase change amount.

摘要： In order to derive distance information according to the phase measuring principle, a periodic signal with at least two, in particular modulated, wavelengths λi are transmitted to two or more objects, their reflections are received again and the associated phases φi are determined and decomposed into their individual object phases φij which are assigned to the J objects. In order to resolve phase ambiguities, an ambiguity interval in which at least one object is located is divided into cells (5) with a defined width, with each cell (5) being assigned a counter reading and a distance. The counter reading is incremented for the cells (5) which are assigned to a possible object distance, with the incrementation being carried out for a periodicity sequential variable and for all the phases. An absolute phase or a true object distance Dj from the at least two objects is determined from the distribution of the counter readings.
