    摘要: A high resolution, low power marine radar for use in applications such as the newly mandated barge/river radars that are to be used in very confined spaces such as canals. An example radar system includes frequency-modulated/continuous-wave (FM/CW) radar that uses very low transmitter power (a fraction of a watt) and has an exceptionally short sensing range of a few feet or even inches if needed.

    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: Systems and methods for reducing radar target processing. The systems include a processor configured to receive a first input from a cooperative surveillance source and a second input from a radar device. The first input includes cooperative target information, the second input includes cooperative and non-cooperative target information, and the processor is configured to process the first and second inputs to remove cooperative target information from the second input based on the first input to generate a modified radar output for use by an output device. The methods include receiving a first input including cooperative target information from a cooperative surveillance source, receiving a second input including cooperative and non-cooperative target information from a radar device, processing the first and second inputs to remove cooperative target information from the second input based on the first input, and generating a modified radar output based on the processed first and second inputs.

    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.

    摘要: Systems and methods for providing passive bird-strike avoidance. A passive L-band receiver system is located on an aircraft. The system includes a processor and an antenna having an array of four or more elements. The antenna configured to receive L-band signals. The processor receives the L-band signals from the antenna, determines if the received L-band signals indicate a target, determines distance, direction of travel and speed of any determined targets, determines if the target is a flock of birds based on the determined speed and determines if a hazard condition exists based on the distance, direction and speed.
