The invention discloses a phased array radar antenna and a detection method thereof, and belongs to the technical field of phased array radars, and the method comprises the steps: designing a radar system to improve the performance, optimize from multiple aspects, select and adapt to the antenna array size and arrangement of radar application, optimize the number and position of units, and determine the configuration through an algorithm to meet the beam detection precision. According to the method, phased array radar electronic control is improved, a high-precision DSP technology is used for regulating and controlling the phase of an antenna unit, the phase adjustment performance is improved to guarantee beam scanning, and a self-adaptive beam forming technology is applied. According to the method, the correlation between the target and the target is cancelled, the target is prevented from following an interference point, the probability of wrong target following is effectively reduced, the correlation judgment accuracy is improved through correlation of multi-dimensional information such as radial speed and echo characteristics, and the target tracking stability is improved while the maneuvering target tracking capability is kept.

The invention belongs to the technical field of power distribution terminal testing, and discloses a traveling wave distance measurement type power distribution terminal testing system, which comprises a signal generation module, and is characterized in that the signal generation module is electrically connected with a data interaction module and a control analysis module, and the data interaction module is electrically connected with the control analysis module through collaborative design of the signal generation module and the control analysis module. The problem that a traditional test system cannot accurately reproduce a complex distribution network scene is effectively solved, on one hand, the multi-channel synchronous traveling wave generator can generate 12 types of fault traveling wave signals of lightning stroke, short circuit and grounding based on the DSP technology, and a 10kV / 20kV distribution network model loaded by the integrated distribution network topology simulator comprises branch lines and distributed power supply nodes; the system can vividly reproduce special working conditions of grounding faults containing photovoltaic access and short-circuit faults under load fluctuation, can only simulate 1-2 types of simple faults compared with a traditional system, improves scene coverage by more than 60%, and ensures that a test result is highly consistent with the actual operation performance of a terminal.

Technology for a device includes a plurality of digital signal processors (DSPs) and a plurality of analog crossbars in communication with the DSPs. The DSPs dynamically adjust queues to optimize data flow based on traffic conditions, latency, and resource availability. Queues may include input queues, output queues, virtual output queues, or hybrid configurations, supporting techniques such as priority scheduling and time-division multiplexing (TDM). The DSPs facilitate flow control through granular backpressure signaling, managing congestion between DSPs and endpoints. Synchronization of queues during crossbar reconfiguration ensures seamless traffic flow and prevents data loss. Advanced mechanisms, such as dynamic queue depth adjustment and adaptive prioritization, enable efficient resource sharing while maintaining high throughput. The device leverages these features to provide scalable, energy-efficient networking solutions for complex environments, such as data centers and telecommunication system
