Abstract

The invention provides an intra-pulse airspace scanning radar system and a receiving and processing method thereof. The system comprises an intra-pulse scanning transmitting module which is configuredto transmit signals through diversified array elements and carry out intra-pulse scanning transmission of an array antenna, an echo signal receiving module configured to receive a target echo signalin a coverage airspace through multi-beam receiving, and an echo signal processing module configured to process the target echo signal through multi-pulse phase-coherent accumulation detection.

Description

technical field [0001] The invention relates to the technical field of radar, in particular to an intrapulse airspace scanning radar system and a receiving and processing method thereof. Background technique [0002] The airspace scanning method of conventional radars may be called pulse-to-pulse scanning. When a conventional radar is working, in order to detect targets in a large airspace range, the radar beam usually scans the airspace. To complete an airspace scan, the radar needs to transmit at least one pulse in each direction until all airspace is covered. Since airspace scanning is realized by transmitting radar pulses in multiple different directions, this airspace scanning method can be called inter-pulse scanning, that is, airspace scanning is completed between pulses, and the main lobe of the beam within a single transmission pulse time points to fixed in a certain direction. [0003] Pulse-to-pulse scanning radar needs to transmit at least one pulse in each di...
