摘要： A method of imaging within an absorptive object comprising: placing transmit and receive antennas in close proximity to a surface of said object; transmitting electromagnetic pulses from the transmit antenna into the object; and receiving a receive signal at the receive antenna simultaneously with the transmit antenna transmitting said pulses; wherein the transmitting and receiving comprises the following steps: a) setting a threshold level for the receive signal strength; b) transmitting one or more pulses; c) comparing the receive signal for said one or more pulses with the threshold level; d) changing the threshold level; e) repeating steps b), c) and optionally d) one or more times. This arrangement can operate at extremely high speed due to the absence of any slow multi-bit ADCs.

摘要： A system and method for high-availability inverse synthetic aperture radar (ISAR). In one embodiment a set of quadratic phase vectors, each corresponding to a different acceleration, is multiplied, one at a time, in a Hadamard product, with a 3 -dimensional data cube, and a fast Fourier transform (FFT) is taken of the result, to form a 2-dimensional array. The two-dimensional array is made sparse by setting to zero elements that fall below a threshold based on a coherency metric, and the sparse arrays are stacked to form a sparse 3- dimensional image. Projections of the sparse 3-dimensional image are formed for presentation to an operator or an image exploitation system.

摘要： The target identification technology described herein includes a method, a system, and a computer program product. In some examples, the system includes a length estimation module configured to determine a length of a target from a radar image based on a range profile, the radar image, and one or more adaptive parameters. The system can include a points of interest module configured to identify at least one point of interest of the target from the radar image based on the length of the target, the range profile, the radar image, the one or more adaptive parameters, and Hough Line processing. The system can include an identification module configured to determine a target identification from a plurality of identification classes based on the length of the target and the at least one point of interest of the target.

摘要： A radar imaging device that receives optical images 330 of a target from varying positions, receives a sequence of radar measurements 340 of the target taken by a radar sensor from varying positions, determines the trajectory of the radar sensor relative to the target based on the optical images, and forms a synthetic aperture radar (SAR) image 370 of the target based on the radar measurements and the determined trajectory. These steps may be repeated to form additional SAR images that form a combined image 390. The additional images may be transformed to common pixel positions based on the corresponding radar trajectories. The radar sensor trajectory may be obtained from the optical sensor trajectory and the position of the radar sensor relative to the optical sensor. The optical sensor trajectory may be determined by tracking the movement of one or more sections of the object. The trajectory may also be based on radar measurements. A model of the shape of the object may be determined. The SAR image may be formed based on pixel positions from the model. A model representation may be superimposed onto the SAR image.

摘要： A radar termed radar 1 is equipped: - with an antenna structure, - with means of transmitting an impulse signal (S1) in a band centred on (F1) according to a repetition period centred on a recurrence period (Tr1) and of pulse width (T1), - with means of receiving signals by the antenna in a frequency band (∆F), - with a unit for processing the signals received on a set of (N) distance bins. The signals received are transmitted by another radar (2) in a frequency band centred on (F2) such that (F2-F1 ≤ ∆F), according to a repetition period centred on a period Tr2 and of pulse width (T2). The signals emitted by the radar 1 and the radar 2 are asynchronous. The method comprises the following steps: - A) slaving of the frequency (F1) to the frequency (F2), by measuring the power received integrated over the set of (N) distance bins and over several recurrences, - B) determination of the period (Tr2 and T2)= and slaving of the period centred on Tr1 to a period centred on (Tr2) with (Tr1 = k Tr2).

摘要： In a method for detecting hidden objects by means of electromagnetic millimeter waves, in which a test object is irradiated with millimeter waves and the millimeter waves that are reflected from the test object are evaluated, the millimeter waves are focused on different depth layers (3, 4) of the test object during the irradiation thereof.
