Radar reflection signal processing device and method

Abstract

The invention provides a radar reflection signal processing device. The device comprises a multiplexing module, a plurality of signal processing modules, a demultiplex module and a trace point extraction module. The multiplexing module is used for receiving multiple beams of reflection signals and used for distribution of the reflection signals. The signal processing modules are used for processing one beam of reflection signals. Each signal processing module comprises a data obtaining module used for receiving one beam of reflection signals and detecting whether information of the reflection signals is lost or not, an impulse interference filter module used for impulse interference filtration, a Doppler processing module used for Doppler filtration, a clutter rejection module used for clutter rejection processing, a mixed constant false alarm detection module used for estimating the noise level, and a noise matching module used for judging whether the noise level is matched or not. The demultiplex module is used for integrating the multiple reflection signals into a data flow. The trace point extraction module is used for generating a trace point picture. In this way, the radar reflection signal processing device can process multiple beams of reflection signals at the same time, and effectively improve the processing ability and speed of radar reflection signals.

Description

technical field [0001] The invention relates to the field of signal processing, in particular to a radar reflection signal processing device and a radar reflection signal processing method. Background technique [0002] In order to protect border security and monitor border security, traditional border security is defended through a large number of fences and walls, as well as through the deployment of a large number of armed forces. With the advancement of technology, border security usually uses active sensors and passive sensors for detection. The system composed of active sensors and passive sensors provides a more effective solution for border security. However, the main The problem is short-range coverage, which is also susceptible to weather conditions. [0003] Among active sensors and passive sensors, radar has relatively good long-range surveillance capabilities and all-weather surveillance capabilities. Signals received by the radar include echoes from waves, ec...
