| 20090109082 | AUGMENTED PASSIVE TRACKING OF A MOVING EMITTER - In one embodiment, the disclosure relates to a method for estimating and predicting a target emitter's kinematics, the method including the steps of: (a) passively sampling, at a first sampling rate, an emitter signal to obtain at least one passively measured signal attribute for estimating the target kinematics; (b) inputting the passively measured signal attribute to an estimator at a first sampling rate; (c) determining a radar duty cycle for active radar measurements as a multiple of the first sampling rate, the multiple defining a duration between radar transmissions; (d) directing a radar system to make active target measurements at the determined duty cycle; (e) inputting to the estimator the active target measurements at the determined duty cycle, while continuously inputting the passively measured signal attributes. | 04-30-2009 |
| 20090303103 | Method and System for Reducing a Leakage Component of a Received Radar Signal - Methods and systems for reducing a leakage component of a received-signal are disclosed. A transmit antenna of a radar system transmits a transmit-signal including a transmit component. A receive antenna of the radar system receives a received-signal including a leakage component and a target component. The received-signal corresponds to the transmit-signal. An overlap determination is made to determine whether the target component overlaps the leakage component and/or is received during a time when the leakage component is expected to be received. If overlap exists, a reduction leakage component (e.g., a previously determined reduction leakage component) is subtracted from the received-signal so as to produce a modified received-signal, the modified received-signal including the target component and substantially excluding the leakage component. If overlap does not exist, an estimate of the leakage component is produced and a reduction leakage component, based at least in part on the leakage component, is produced. | 12-10-2009 |
| 20110109492 | SIGNAL PROCESSING DEVICE, RADAR APPARATUS AND SIGNAL PROCESSING PROGRAM - This disclosure provides a signal processing device, which includes a reception signal acquiring module for acquiring reception signals received by a radar antenna, an identifying module for identifying a kind of each reception signal, an extracting module for extracting the reception signal for each kind, and a kind-base signal processing module for performing individual signal processing for each kind of the extracted reception signal. | 05-12-2011 |
