Abstract

The invention discloses an intelligent imaging system of a millimeter wave radar. The system comprises an A / D collection module, a digital correlator module and an algorithm and control module; the nA / D collection module collects paths of orthogonal intermediate-frequency I and Q analog signals in a receiver channel, the orthogonal intermediate-frequency I and Q analog signals are quantified andcorrelated to generate a visibility function via the digital correlator module and the algorithm and control module, imaging via inversion is carried out, and a bright temperature distribution image after inversion is carried out. The algorithm and control module carries out calibration of imbalance voltage, power measurement, system calibration and inversion imaging on the signals, and outputs the bright temperature distribution image after inversion.

Description

technical field [0001] The invention belongs to the technical field of radar data processing, in particular to a real-time digital signal processing system for millimeter wave synthetic aperture imaging radar. Background technique [0002] Digital signal processing technology has been widely used in the fields of communication, radar, sonar, remote sensing, graphics and image processing, and speech processing. For increasingly complex two-dimensional, three-dimensional and even four-dimensional image processing, it is necessary for the processing system to be able to run complex algorithms. . For high-end equipment such as communications and radar, it is necessary to complete signal processing and analysis in a very short period of time, and the requirements for processor performance are getting higher and higher. For example, voice algorithms need to complete tens of millions to hundreds of millions of operations per second, video and image algorithms It needs to complete ...
