摘要： A frequency surveillance method for monitoring background atmospheric noise levels in unoccupied channels in an operating frequency band of a high frequency communication system. In the method, the unoccupied channels are scanned a number of times to obtain analogue signals. The obtained signals are transformed to a digital form and averaged. The averaged digital signals are filtered to remove substantially all radio frequency interference. Absolute signals are then produced by scaling or comparing the filtered signals with a known noise level. The background noise levels are obtained by further averaging the absolute signals. A visual display unit is used to display the background noise levels as functions of frequencies. A frequency surveillance apparatus is also disclosed.

摘要： A passive channel calibration method based on a non-linear antenna array sets an antenna array to a non-linear formation that contains at least a combination of translation invariant dual array-element couples, detects single-azimuth ocean echoes via combinations of translation invariant dual array-element couples, estimates channel amplitude mismatch coefficients via the single-azimuth ocean echoes to implement amplitude calibration, and estimates channel phase mismatch coefficients via the single-azimuth ocean echoes after amplitude calibration and the known array position information to implement phase calibration. The method does not need any auxiliary signal source and so is a genuine passive channel calibration method. Advantages of the invention are: the troublesome problems encountered by active channel calibration methods, such as ship echo interference, multi-path effect and so on do not exist; utilizing a great number (may more than 100) of high strength single-azimuth ocean echoes, and so having good precision and steadiness; having less computing load; being able to operate stably without stopping for a long time; greatly improving the application flexibility of HFSWRs; and improving detection performance, as well as greatly reducing development and maintenance costs.

摘要： A radio location system comprises a wireless transmitter (16) that outputs two megahertz period bursts of two gigahertz radar carrier signals. A receiver system (18, 20, 22) determines the position of the transmitter by the relative arrival of the radar bursts at several component receivers set up to have a favorable geometry and each one having a known location. One receiver provides a synchronizing gating pulse to itself and all the other receivers to sample the ether for the radar pulse. The rate of the synchronizing gating pulse is slightly offset from the rate of the radar bursts themselves, so that each sample collects one finely-detailed piece of information about the time-of-flight of the radar pulse to each receiver each pulse period. Thousands of sequential pulse periods provide corresponding thousands of pieces of information about the time-of-flight of the radar pulse to each receiver, in expanded, not real time.

摘要： An ultrawide (UWB) receiver utilizes a strobed input line (14) with a sampler (10) connected to an amplifier (18). In a differential configuration (18), +UWB inputs (14a) are connected to separate antennas or to two halves of a dipole antenna. The two input lines (14) include samplers (10) which are commonly strobed (12) by a gating pulse with a very low duty cycle. In a single ended configuration, only a single strobe input line and sampler is utilized. The samples integrate, or average, up to 10,000 pulses to achieve high sensitivity and good rejection of uncorrelated signals.

摘要： A bi-static radar configuration measures the direct time-of-flight of a transmitted RF pulse and is capable of measuring this time-of-flight with a jitter on the order of about one pico-second, or about 0.01 inch of free space distance for an electromagnetic pulse over a range of about one to ten feet. A transmitter (53) transmits a sequence of electromagnetic pulses in response to a transmit timing signal, and a receiver (58) samples the sequence of electromagnetic pulses with controlled timing response to the samples. A timing circuit supplies the transmit timing signal to the transmitter and supplies the receive timing signal to the receiver. The receive timing signal causes the receiver to sample the sequence of electromagnetic pulses such that the time between transmission of pulses in the sequence and sampling by the receiver sweeps over a range of delays.
