摘要： A system includes a storing module configured to receive records. The records include dynamic frequency selection (DFS) information. A data extraction module is configured to extract the DFS information from a first plurality of the records. A control module is configured to determine whether the DFS information in each of the first plurality of records is a radar signal and generate a radar detected signal when at least a first predetermined number of the first plurality of records are a first type of radar signal. A polling module is configured to selectively poll the storing module for additional records received after the first plurality of records when at least a second predetermined number and less than the first predetermined number of the first plurality records are the first type of radar signal.

摘要： A system includes a sampling module, a counter module, and a frequency characteristic module. The sampling module samples radio frequency (RF) signals on a first channel for a first predetermined period and a second predetermined period that is subsequent to the first predetermined period. The counter module increments first and second counts when the samples collected during the first and second predetermined periods reverse polarity, respectively. The frequency characteristic module determines a frequency of the RF signal based on at least one of the first and the second counts and determines frequency variation of the RF signal based on the first and second counts.

摘要： A single chip radio transceiver includes circuitry that enables detection of radar signals to enable the radio transceiver to halt communications in overlapping communication bands to avoid interference with the radar transmitting the radar pulses. The radio transceiver is operable to evaluate a number of most and second most common pulse interval values to determine whether a traditional radar signal is present. The radio transceiver also is operable to FM demodulate an incoming signal to determine whether a non-traditional radar signal, such as a bin-5 radar signal, is present. After FM demodulation, the signal is averaged wherein a substantially large value is produced for non-traditional radar signals and a value approximately equal to zero is produced for a communication signal that is not FM modulated with a continuously increasing frequency signal. Gain control is used to limit incoming signal magnitude to a specified range of magnitudes.

摘要： A system and method for providing radar signal detection in a communications system. In an example method, a raw energy detect signal is received and analyzed to determine if the raw energy detect signal contains a valid radar pulse. A bit is stored in a bit sequence storage device such that the bit has a first value if a valid radar pulse was detected or a second value indicating that a valid pulse was not detected. A set of bits in the bit sequence storage device are accessed to determine if a plurality of waveform-indicating locations in the bit sequence storage device includes valid pulses. In another aspect of the invention, a system detects a radar signal in a communications device. The system includes a pulse detector to detect pulses in a raw energy signal having a pulse width within a predetermined minimum and maximum pulse width. The system includes a frequency detector having a bit sequence storage device to store the bits output by the pulse detector. The frequency detector detects whether the detected pulses conform to a waveform type by determining if the bits are stored in the bit sequence storage device in waveform-indicating locations.

摘要： A system includes a first-in first-out (FIFO) module, a polling module, a data extraction module, and a control module. The FIFO module receives records having dynamic frequency selection (DFS) information generated based on pulses received and generates a control signal for every N of the records received, where N is an integer greater than or equal to 1. The polling module selectively polls the FIFO module and reads M of the records received by the FIFO module, where M is an integer greater than or equal to 1 and less than N. The data extraction module extracts the DFS information from the N records when the control signal is received and selectively extracts the DFS information from the M records. The control module determines whether the pulses are a type of radar based on the DFS information extracted from at least N of the (N+M) of the records.

摘要： A single chip radio transceiver includes circuitry that enables detection of radar signals to enable the radio transceiver to halt communications in overlapping communication bands to avoid interference with the radar transmitting the radar pulses. One design goal, however, is to avoid false triggers that result from spurious tones and omissions and that further detects radar signals even in circumstances in which a radar pulse has been masked or eliminated by interference. Accordingly, the radar detection block includes circuitry for detecting and measuring the radar signals in the presence of such interference. More specifically, the radar detection block includes a moving average filter, a threshold comparison state machine, and radar detection logic within software that is executed by a processor for determining whether a radar signal is present.
