Firstly, radar echoes are formed into a first in first out queue, and short time slip window coherent integration is implemented.
首先,将雷达的回波信号构成一个先入先出的队列,进行短时滑窗相参积累。Meanwhile, we regard coherent excited strong coupled antennas like CFA, EH, as "unconventional" electrically small antennas.
同时将CFA、EH等强耦合相参激励下的电小天线称为“非传统”电小天线。Because of its inherent advantages, W band coherent radar have been widely used in speed detection and imaging.
W波段相参雷达因其固有的优势被广泛应用在测速、测距和成像之中。In order to enhance the anti-jamming ability of a radar system, a new signal form used in coherent polarization agility radar is proposed.
为了提高雷达系统对抗电子干扰的能力,提出了一种新型相参极化捷变雷达信号。The basic theory of signal processing in Pulse-Doppler radar was introduced systematically in chapter two.
第二章系统地阐述了脉冲多普勒雷达的相参信号处理的基本理论。However, the phase errors destroy the coherence of stepped frequency signal, which increase the amplitude of sidelobe.
随机相位误差的存在,破坏了频率步进信号的相参性,导致合成高分辨结果旁瓣峰值电平提高,噪声基底抬高。The principle of moving target detecting and coherent integrating with Doppler filters was analyzed secondly.
然后分析了脉冲多普勒雷达利用多普勒滤波器进行动目标检测和相参积累的原理。The W-band coherent Doppler radar has high precision. It is widely used in speed measuring.
W波段连续波相参多普勒雷达具有测速精度高的优点,广泛应用于多种测速场合。The coherent-noise jamming signal has the same structure with the radar transmit signal and the same jamming ability with noise signal.
