Abstract

Synthetic impulse and aperture radar (SIAR) is new kind of advanced meter wave radar. Stealth techniques and anti-radiation missiles (ARM) raise challenges to military radar. Many research results show that meter (or much longer) wavelength electromagnetic waves are the right way against the stealth technique and ARMs. However, traditional meter wave radar has many disadvantages, such as poor angle resolution, weakness against ECM, low measurement precision etc. The new concept of synthetic impulse and aperture radar was presented, by J. Dorey et al. (see Colloque International sur le Radar, p.556-62, 1989). SIAR has no scanning mechanism or phased devices. The beams or antenna patterns of both the transmitting array and the receiving array are formed by digital calculation. SIAR can keep the advantages of traditional meter wave radar and overcome most of its disadvantages. This new kind of radar has many other advantages, for example, low probabilities of interception (LPI), capacity of long coherent integration of targets and fine Doppler resolution, high feasibility of system processing, etc. The basic concepts of SIAR and some experimental results are introduced.

一种新型先进米波雷达的研究

合成脉冲孔径雷达(SIAR)是一种新型的先进米波雷达。隐身技术和反辐射导弹(ARM)对军用雷达提出了挑战。许多研究结果表明，米(或更长的)波长的电磁波是对抗隐身技术和武器的正确途径。然而，传统的米波雷达存在着角度分辨率差、抗干扰能力差、测量精度低等缺点。J. Dorey等人提出了合成脉冲和孔径雷达的新概念(见国际雷达研讨会，第556-62页，1989年)。SIAR没有扫描机构或相控装置。发射阵列和接收阵列的波束或天线方向图均通过数字计算形成。SIAR既保留了传统米波雷达的优点，又克服了传统米波雷达的大部分缺点。这种新型雷达具有截获概率低、目标长相干积分能力强、多普勒分辨率高、系统处理可行性高等优点。介绍了SIAR的基本概念和一些实验结果。
