摘要： Systems and methods for testing a signal generated by a Direct Digital Synthesizer (DDS) in a radar altimeter. In an embodiment of the method, a voltage signal derived by comparing a fixed reference frequency to a ramped frequency signal generated by the DDS based on a clock-based reference signal is generated. The generated voltage signal is integrated over a predefined range of clock signals. The integration is sampled at a previously defined clock tick. The sample is compared to a desired value and an indication that the radar altimeter is malfunctioning is provided if the comparison exceeds a predefined threshold value. The radar altimeter system is deactivated if an indication that the radar altimeter is malfunctioning has been provided.

摘要： A proximity sensor may be used as part of a vehicle blind spot detection system. The sensor is configured to transmit multiple radio frequency (RF) signals of different frequencies, receive reflected RF signals, and supply intermediate frequency (IF) signals. Each IF signal is representative of one of the reflected RF signals, and each reflected RF signal corresponds to a transmitted RF signal that was reflected by an object within the sensor detection region. The sensor uses the IF signals to determine whether an object is within its detection region and its movement direction.

摘要： Methods and apparatus for determining an altitude with an altimeter is provided. One method includes transmitting a signal having a fixed modulation period towards a ground target and then detecting reflected signals off the ground target. The method then implements a single Fast Fourier Transform (FFT) on the detected signals for each modulation period that computes all possible altitudes in real time. A short history of the real time altitude calculations is collected and then the altitude based on the short history of the real time altitude calculations is determined.
