双语例句
- A combination method based on secondary mixing and MTD ( Moving Target Detection) processing is proposed for high-speed targets detection in linear frequency-modulated continuous wave ( LFMCW) radar.
针对LFMCW雷达高速运动目标的检测问题，本文提出了一种二次混频与MTD处理相结合的方法。 - According to the moving target's echo characteristics acquired by the frequency-modulated stepping radar, the envelope migration is firstly carried out for the subset of the compressed pulse.
根据调频步进雷达运动目标的回波特性，首先对压缩后的子脉冲进行包络平移。 - Linear frequency-modulated ( LFM, chirp) signal that is often applied in radar, sonar and communications system is nonstationary signal, in which the frequency varies with time.
应用于雷达、声纳和通信等信息系统中的线性调频（LFM，chirp）信号是非平稳信号，即频率成分是随时间变化的。 - Linear frequency-modulated continuous wave synthetic aperture radar ( LFM CW SAR) imaging algorithm is studied.
研究了线性调频连续波SAR的距离徙动算法成像。 - Effect of the linearity on range resolution of linear frequency-modulated radar
线性度对线性调频雷达距离分辨力的影响 - The result shows that the anti-barrage-jamming ability of ISAR is a little bad compared with conventional linear frequency-modulated radar and SAR, because motion compensation must be done in ISAR imaging.
研究结果表明，由于ISAR成像必须经过运动补偿处理，这一弱点使其抗压制干扰能力相对较差。 - Study chaos-based frequency-modulated signals and the corresponding radar system design.
