摘要： Techniques are disclosed for detection and ranging systems and methods to improve range resolution, target separation, and reliability. A method includes selectively attenuating a signal representing a ranging system return or echo from targets so as to suppress side lobes or other undesirable artifacts appearing in the signal due to noise, interference, and/or distortion. A method may additionally or alternatively include rejecting interference events in ranging system returns by comparing a received return with that expected from a target illuminated by the ranging system, as determined by characteristics of its particular ranging sensor, and rejecting or attenuating returns or portions of returns that fail to match those characteristics in time or space. A system configured to perform such methods and comprising a transducer/antenna, a transceiver, a controller, and/or other logic devices implementing a pulse generator, correlator, selective attenuator, comparator, buffer, subtractor, and/or output circuit is also disclosed.

摘要： A method includes receiving from multiple transducers (28) respective signals including reflections of a transmitted signal from a target. An image (42) of the target is produced irrespective of sparsity of the received signals, by computing transducer-specific frequency-domain coefficients for each of the received signals, deriving, from the transducer-specific frequency-domain coefficients, beamforming frequency-domain coefficients of a beamformed signal in which the reflections received from a selected direction relative to the transducers are emphasized, and reconstructing the image of the target at the selected direction based on the beamforming frequency-domain coefficients.

摘要： The invention relates to a method for determining parameters of a finite impulse response pulse compression filter, implemented by a multichannel radar. The method includes: a step Etp10 of transmitting a calibration signal and of acquiring this calibration signal after propagation through the transmission channel; a step Etp20 of injecting the acquired signal, at the input of each of the receiving channels; a step Etp30 of measuring the signal at the output of each receiving channel; a step Etp40 of calculating the transfer function of the matched filters (H
s , H
d ) from the signals at the output of the receiving channels; and a step Etp50 of measuring the value of the average power at the output of the different receiving channels and of calculating the relative increases between each of the receiving channels and a predetermined receiving channel from said measured average power values.

摘要： The invention is to make so as to reduce as far as possible a detection leak in a case detecting a body having entered into a predetermined range. A pulse sensor having a first reception system and a second reception system is adopted in regard to one transmission system. And, a detection distance of the first reception system is set to about 0.75 [m] for instance. By this, a characteristic of a lowest reception sensitivity of the first reception system becomes a curve Seta. Further, about 0.05 [m] which has been deviated, in regard to the detection distance of the first reception system, by a distance corresponding to a half-wavelength of a wave of a main frequency within a transmission signal to which a band restriction from a transmission system has been applied is set as the detection distance of the second reception system. By this, the characteristic of the lowest reception sensitivity of the second reception system becomes a curve Setb. As a result, a detection of the body existing in distance ranges D2 to D5 becomes possible. The present invention can be applied to the pulse sensor.

摘要： An object detection device includes a transmitting unit that transmits a transmission wave, a receiving unit that receives a reception wave produced by the reflection of the transmission wave off an object, a CFAR processing unit that acquires a difference value between a processing target value that is the value of a processing target signal corresponding to the reception wave received at a certain detection timing, and a reference value based on a moving average value of the values of reference signal groups corresponding to the reception wave received during predetermined periods before and after the detection timing, a detection processing unit that generates information about the object, based on the difference value, and a setting unit that selects the reference value suitable for a detection distance corresponding to the detection timing from a plurality of the reference values.
