摘要： A method for detecting, by means of radar techniques, objects immersed in a material, which uses an antenna, or an array of antennas, driven by a first and a second circuit that generate respectively reception and transmission triggering signals in a digital domain and then convert them into analog pulses respectively of periods T and T+S. Two identical circuits (10' and 10") are used for generating respectively transmission and reception triggering pulses (20' and 20"). They are operated in parallel by a microcontroller (21) that administers said first and second circuit supplying as input to them respectively a first counting duration (11') and a second counting duration (11") that are different from each other for a numerical value derived from said periods T and T+S. This way, the periodic signal (17') resulting from said first circuit (10') and the periodic signal (17") resulting from said second circuit (10") have respectively a first and a second frequency f(l) and f(2) that are different from each other for a frequency value derived from said range S. The timing circuit carrying out a sample-conversion of the frequency of the received signals not subject to misadjustment of the time scale and much more flexible concerning the programmation of time setting.

摘要： A method for interferometric radar measurements that provides prearranging, at a target observed by the radar, of a transponder that is adapted to perform a frequency shift f d of a radar signal received by the target, and to retransmit a response signal towards the radar. The frequency-shift is such that the signal (21), as received by the radar, can be separated from clutter (19) coming from the radar scenario, by a demodulation step (A), in particular a coherent demodulation step, and a phase extraction step (B), which may comprise a further demodulation step by a phasor that has a frequency equal to f d . If these steps are carried out subsequently, it is possible to calculate the phase difference with respect to signals 22 and then measuring the displacement that target (2) carries out between such instants. In case of a plurality of targets in a same radar scenario, the use of a corresponding plurality of transponders with specific frequency-shifts allows separately demodulating the signals coming from each transponder. In case of variable frequency radar signals, in particular if the frequency is increased according to a predetermined pitch, i.e. a frequency step, the phase extracting step may provide sampling sequences of values of the response signal coming from respective resolution cells of the radar scenario, and applying the inverse discrete Fourier transform to such sequences, in order to display the target in a resolution cell that is located between a maximum distance available by the radar and the limit of range unambiguous. The method allows overcoming well-known prior art interferometric radar systems drawbacks, since it eliminates clutter, and allows resolving more target in a same radar scenario, or in a same resolution cell.
摘要翻译：一种用于干涉雷达测量的方法，其在由雷达观测到的目标处提供适于执行由目标接收的雷达信号的频移fd并且向雷达重新传送响应信号的应答器的预排列。频移使得由雷达接收的信号（21）可以通过解调步骤（A），特别是相干解调步骤与来自雷达情景的杂波（19）分离，并且相位提取步骤（B），其可以包括具有等于fd的频率的相量的另外的解调步骤。如果随后执行这些步骤，则可以计算相对于信号22的相位差，然后测量目标（2）在这种瞬间之间执行的位移。在相同雷达情况下的多个目标的情况下，使用具有特定频率偏移的相应多个转发器允许单独解调来自每个应答器的信号。在可变频雷达信号的情况下，特别是如果根据预定音调（即频率步长）增加频率，则相位提取步骤可以提供来自雷达情景的相应分辨率单元的响应信号的采样序列，以及将这种逆离散付里叶变换应用于这样的序列，以便在位于雷达可用的最大距离和范围界限之间的分辨率小区中显示目标。该方法允许克服众所周知的现有技术的干涉测量雷达系统的缺点，因为它消除了杂波，并且允许在相同的雷达场景或相同的分辨率小区中分辨更多的目标。
