摘要： A retrofit system applied to existing FMCW radars in order to convert them into pulsed linear frequency-modulated radars with the ability to dynamically switch between two pulsed modes and an FMCW mode based on the estimated range of a target. This retrofit also includes provisions for adaptively configuring chirp and sweep parameters to optimize range resolution. The result is a retrofit system capable of converting an FMCW radar into a dual pulsed mode radar with adaptive sweep configuration.

摘要： A method, apparatus, system, and computer program product for evaluating a maturity of a model for a product. A selected maturity state is determined by a computer system for the model for evaluation. A determination is made by the computer system as to whether the model meets a set of criteria for the selected maturity state and a confidence level for the selected maturity state. A model action is performed by the computer system using the model when the model meets the set of criteria for the selected maturity state and the confidence level for the selected maturity state.

摘要： In examples, systems and methods for increasing the performance of electrically-small antennas are described. An example system comprises an electrically-small antenna having an antenna feed. The electrically-small antenna is configured to receive a signal. The system also comprises a non-foster circuit having a negative capacitance coupled to the antenna feed in a shunt position. The non-foster circuit is configured to resonate the electrically-small antenna and provide a voltage increase to the received signal. The system also comprises a buffer circuit configured to provide an impedance conversion of the voltage-increased received signal between the antenna feed and an output of the buffer circuit. The buffer circuit includes a field-effect transistor.

摘要： An electronically steerable phased array and switching network connected to an FMCW radar transceiver to enable a low-cost monopulse tracking system that covers a wide field of regard using electronic beam steering. In a first mode, beamformer integrated circuits (BFICs) at each element in the array are switched synchronously with transmit/receive (T/R) switches located at the subarray level. This allows the entire aperture to be switched between transmission and reception, enabling the FMCW radar transceiver to be operated in a pulsed configuration. In a second mode, a portion of the T/R switches at the subarray level and all of the connecting BFICs at the element level are fixed in either transmitting or receiving mode, allowing separate portions of the aperture to concurrently transmit or receive. The arrangement of transmitting and receiving subarrays can be dynamically reconfigured to allow for accurate bearing and azimuth estimation using alternating monopulse.
