摘要： A radar device includes transmission signal generation circuitry that generates one or more transmission signals, a transmission amplifier that amplifies a power level of the one or more transmission signals, a transmission gain controller that adjusts a gain of the transmission amplifier, transmission antenna circuitry that converts each of the one or more amplified transmission signals into each of one or more radio signals and transmit the one or more radio signals to a measurement target space, reception antenna circuitry that receives the one or more radio signals from the measurement target space, and one or more receivers that detect a power level of a transmission/reception leakage signal using the one or more received radio signals. The transmission gain controller adjusts the gain of the transmission amplifier in accordance with a result of comparison between the detected power level and a power level of a transmission/reception leakage signal measured in advance.

摘要： Methods, systems, apparatuses, and computer program products are provided for detecting objects, including humans, using a mobile communications device. A communication space is scanned with a beam-shaped signal transmitted by a phased antenna array of the mobile communications device. Information is discerned from one or more attenuated signals received from the communication space based on the beam-shaped signal. The information is analyzed to determine an object in the communication space. Whether the object is likely at least a portion of a human is determined. A communication signal transmitted by the phased antenna array is modified in response to determining that the object is likely at least a portion of a human, and that the at least a portion of the human has a predetermined spatial relationship with the phased antenna array.

摘要： A radar apparatus measures at least one characteristic of at least one object even in a near field. A sweep generator generates a sweep signal to modulate an oscillator to generate a varying frequency signal. A transmitter transmits the varying frequency signal as a radar signal. A receiver receives a reflected radar signal to produce a received signal using the varying frequency signal. A compensation signal memory holds a previously stored compensation signal. A compensation circuit compensates the received signal based on the previously stored compensation signal to produce a compensated received signal. A frequency transformation circuit transforms the compensated received signal to produce a frequency spectrum signal. A peak detector measures the characteristic of the object based on a peak of the frequency spectrum signal. When operating in a calibration mode and the reflected radar signal is quieted, the received signal is written into the compensation signal memory.

摘要： A pulsed radar method of sensing or measuring a product material in a storage tank. A plurality of waveform types are automatically selected based on a power limitation. The pulsed radar signal is transmitted by a programmable transmitter to the product material, wherein the pulsed radar signal is reflected or scattered by the product material to provide a radar signal during an interval of time including a target signal. An initial gain or attenuation is automatically set for a programmable receiver. The programmable receiver receives the radar signal including the target signal during the interval of time, and the target signal is signal processed using a lower attenuation setting as compared to the initial gain or attenuation to determine at least one parameter associated with the product material. The transmitted and received radar signal can also be adjusted according to the measured SNR.

摘要： Three methods are used to minimize the interference between multiple FMCW radars. The first, basic method is to use spread spectrum waveforms which differ for each radar. The FMCW waveforms have different modulation slopes for each frequency excursion. The waveforms also have different center frequencies for each excursion thus in total spreading the spectrum in frequency and modulation slope. The second method used is to control the power output for FMCW radars which have narrow beam scanning antennas, according to the azimuth position of the antenna. The third method is to select separate frequency bands for any interference which would still be above threshold. Selection would be by either infrastructure information or by comparison of "own" radar code to that received from each interfering radar over a separate, but related modulated CW transmission.
摘要翻译： 使用三种方法来最小化多个FMCW雷达之间的干扰。 第一种基本方法是使用每个雷达不同的扩频波形。 对于每个频率偏移，FMCW波形具有不同的调制斜率。 波形对于每个偏移也具有不同的中心频率，因此在频谱和调制斜率中总共扩展频谱。 所使用的第二种方法是根据天线的方位位置来控制具有窄波束扫描天线的FMCW雷达的功率输出。 第三种方法是为仍然高于阈值的任何干扰选择单独的频带。 选择是通过基础设施信息，或通过比较“自己”的雷达编码与从每个干扰雷达接收到的单独的但相关的调制的CW传输。
