Abstract: A method provides for identifying short radar signals in presence of interfering signals from various sources applicable to U-NII devices. The method includes collecting a set of information about received interfering signals until the End-Of-Burst (EOB) condition is identified. When the EOB is identified, the set information about the received train of interfering signals is processed.

Pulses matching the criteria are considered as potential radar pulses. When at least one pulse has been identified as a potential radar pulse for a number of times larger than a predefined limit, it is concluded that that pulse has been generated by a radar installation.

Abstract: A method is provided for coordinating detection of emitted signals by a receiver with transmission of signals by a transmitter, wherein the receiver and the transmitter are located on the same platform. The receiver scans a surrounding environment to detect emitted signals in multiple frequency ranges while the transmitter transmits signals in a predetermined frequency range. The receiver may employ dwells which may be defined as receiver configurations. A dwell, when executed, may be used to detect signals in a certain frequency range.

If the frequency range of the dwell is such that transmitter signals do not interfere with execution of the dwell, the dwell can be executed.
