摘要： An imaging system comprises a transmitter (24, 25), a receiver (24, 25, 21), and a controller (20) for directing the transmitter and the receiver to scan an object in a volume. The controller determines which sub-volumes of the volume the object is located within and then performs a fine scan in those sub-volumes. This reduces overall scanning time. The controller (20) may compare a received signal sample magnitude from the initial scan with a threshold to make the decision. The initial scan may be performed with a spot size to include only one or more particular volume elements within at least some of the sub-volumes.

摘要： Electrical properties of concealed dielectric objects, such as the dielectric permittivity, can be deduced from incident, reflected, and transmitted electromagnetic waves in an imaging system. In a confocal arrangement a horn illuminates a reflect array and the reflect array is configured to focus the radiation at an element in the scan volume. The reflections are in turn refocused by a reflect array at the horn aperture. The reflect array is electronically configured to scan the focal point throughout the scan volume in a systematic way. Knowledge of the horn pattern and the scan strategy allows the system to compute the geometry associated with each volume element. Amplitude and phase variations between the object and the surrounding volume and the computed geometry are used to estimate the relative permittivity and thus facilitate categorization of the object using a database of material relative permittivities.

摘要： An upconverter receives an intermediate frequency (IF) modulated signal on a port (5) and a local oscillator carrier signal at a port (6). A comb generator (13-15) generates a comb-like waveform from the carrier signal, the waveform having a peak for each of a number of multiples of the carrier fundamental. A bandpass filter (16) selects one of the comb peaks and there is further multiplication at a quadrupler (20). The modulated signal (IF) and the multiplied carrier are mixed in a mixer (23) to provide a high frequency upper sideband (LO+IF) output. The output is transmitted in a waveguide (7) which is integral with the casing (2, 3) and which performs high frequency filtering by virtue of its shape.

摘要： An imaging system (1) comprises an antenna array (2), 24 GHz transceivers (3), and a digital receiver (4) including an ADC and circuits for filtering. The digital receives commands from the host PC (5) and passes data to the host PC (5) for display. The host PC 5 initiates volume scans, performs system diagnostics and error reporting, and collects scan data and displays it for the operator. The digital receiver (4) presents the scan requests to the antenna array (2) in a synchronised manner. All control signals in the antenna array are presented via a presentation clock (an individual presentation clock being generated for sub-sections of the array; of the order of five hundred presentation clocks are generated). The spectral content of each presentation clock is adjusted via a spreading circuit, thus adjusting the spectral interference radiated through the printed circuit board traces to the FET elements that each presentation clock feeds. The spreading clock generation circuit include taps (Tap 1, Tap 2 . . . Tap N) on a delay line, feeding a multiplexer. Delayed versions of the master clock are switched onto the presentation clock in a given sequence such that the presentation clock is composed of different phases of the master clock. This alters the spectral content of the presentation clocks with respect to the master clock, lowering the power at the fundamental frequency. This in turn lowers the power at the harmonics of the fundamental, reducing the electromagnetic radiation across the spectrum. The presentation clocks may be offset in their spreading pattern and hence in their presentation frequency such that the electromagnetic radiation is further reduced.

Tap N），馈送多路复用器。主时钟的延迟版本以给定的顺序被切换到呈现时钟，使得呈现时钟由主时钟的不同相位组成。这相对于主时钟改变呈现时钟的频谱内容，降低基频处的功率。这反过来降低了基波谐波的功率，从而减少了整个频谱的电磁辐射。呈现时钟可以在它们的扩展模式中偏移，并因此在其呈现频率上偏移，使得电磁辐射进一步减小。
