该系统制造简单,但需要小心谨慎才能获得高精度。 FMCW 具有与脉冲压缩( pulse compression)相同的概念基础。虽然还有其他形式的频率调制,例如正弦和非线性(sinusoidal and nonlinear) FM,但我们专注于线性情况(线性FMCW),因为它可以引入关键原理,并且是当今 CW 雷达系统中最广泛使用的调制形式 未调制 CW 雷达的一个缺点...
定义(脉冲压缩Pulse Compression) 在不降低PTx的情况下增加带宽称为脉冲压缩(Pulse Compression) 脉冲压缩允许雷达系统传输相对较长的持续时间和低峰值功率的脉冲,以获得短脉冲、高峰值功率系统的距离分辨率和探测性能(to attain the range resolution and detection performance of a short-pulse, high-peak power system...

High-range resolution is achieved by wideband pulse compression, time band-width exchange, or frequency stepping waveforms, which relieve the need for ultrafast analog-to-digital conversion. With a target aircraft range of 90 km, wing and fuselage are quite evident, and during 80 seconds of ...

For the case of the linear frequency modulated (LFM) pulse compression radars, mathematic principles of the interrupted-sampling repeater jamming is developed, and then the efficiency of the jamming is described and stated as expressions of key parameters which are also beneficial to the jamming ...
Each way of signal is transmitted independently. Figure 9-28 Multiplexing and demultiplexing for TDM Traditional Transmission Mode After processed by Pulse Code Modulation (PCM), voice signals, together with other digital signals, are transmitted through Plesiochronous Digital Hierarchy (PDH) or ...
What is important to see here is that the geometric Pythagorean representation of competing velocities also represents an aerodynamic/hydrodynamic-like compression of the medium in front of the traveling matter object. The region in front of the craft is called the bow shock, which is compressed me...
