OFDM-MIMO相控阵雷达性能分析
Performance Analysis of OFDM-MIMO Phased Array Radar
摘要
Abstract
MIMO phased array radar using the OFDM waveforms is a new kind of MIMO radar, which can achieve the waveform diversity and frequency diversity simultaneously. Howeve, differing from the orthogonal phase-coding waveforms, OFDM signals have a different centre frequency and occur a specific beat frequency, thus resulting in the processing of the OFDM waveforms-based MIMO radar signals being more complicated. To solve this problem, at first, this paper sets up a model for this radar system and derives the coherent combination results of space domain between sub-arrays, and then, analyzes the SNR, operating range and anti-interception performances of the system, and compares them with those of conventional phased-array radar. Theoretical analysis and simulation experiment prove this proposed new system to be of advantages.关键词
