摘要： The present invention relates a method of improving a radar system, a module for improving a radar system and an improved radar system that are more efficient than current radar systems and methods of using same. Specifically, in the context of space-time adaptive processing at high angle-doppler resolutions, this advanced radar system utilizes an improved estimator of the interference covariance matrix together with the plug-in whiten-then-match filter. This improvement (a) roughly optimizes the output signal-to-interference-plus-noise, thereby increasing the probability of accurately detecting targets' angular positions and radial velocities, (b) maintains a roughly constant, and thus controllable, false alarm rate, and (c) sometimes associates data preprocessing steps with a Reed-Mallett-Brennan detection loss, providing a guideline for rejecting certain preprocessing steps. Collectively, these advancements signify a considerable leap forward in radar technology.

摘要： The emergency egress apparatus includes a protuberance mated to a first portion of the door barricade and a keeper mated to a second portion of the door barricade. A retainer is selectively disposed between one of two positions. A first position defines the placement of the retainer that establishes an interference fit between the protuberance and the keeper. A second position defines the placement of the retainer such that it is not in contact with the protuberance or the keeper. The first position secures the first portion of the door barricaded with respect to the second portion of the door barricade, and the second position decouples the first portion of the door barricade with respect to the second portion of the door barricade

摘要： In a system of receivers and transmitters, a mixed-mode distributed coherent aperture technique includes receiving a combination of separable transmit waveforms; processing the combination of separable transmit waveforms to estimate coherence parameters associated with each separable transmit waveform of the combination of separable transmit waveforms; based on an estimation of the coherence parameters, determining a signal model of a next set of transmissions of the separable transmit waveforms transmitted by a plurality of transmitters; processing the signal model according to a mixed-mode distributed coherent radar operating mode that is a function of coherence parameter errors associated with each separable transmit waveform and a size of the sub-array; and sending the processed signal model to the plurality of transmitters for each transmitter to generate its own separable transmit waveform selected from the separable waveforms for transmission.
