Integration of radar and communication (IRC) is conducive to improving hardware resource utilization and spectrum utilization. This paper proposes a joint range and velocity estimation method for IRC based on multi鈥恠ymbol orthogonal frequency division multiplexing (OFDM) radar pulses. A two鈥恠tep ...

CHAPTER 2 脉冲集成(Pulse Integration)(十) 第一章在雷达测量(radar measurements)的背景下讨论了脉冲积分。在本节中,将在雷达探测(radar detection)的背景下对该主题进行更全面的分析。先前提出的总体原则和结…
It is well known that the range resolution [6] is inversely proportional to the bandwidth of transmitted pulses. The PD radar can be divided into two categories [7]: narrowband and wideband. In the context of white complex Gaussian noise, this paper deals with the problem of detecting the ...
In a radio-frequency radar system, a radar antenna (12) irradiates a region to be monitored, and antenna elements (14a-p) arrayed irregularly about a mobile platform (10) receive the resultant echo signal, which mixers (18 and 21) translate in frequency, coherently with the transmitted signa...
Objective Based on the adaptability test requirement of radar pulse transient interference environment for ground platform system, a moveable intensive electromagnetic pulse interference simulation test system is studied. Methods System basic composition is studied, and the three key indicators affecting test...

Target detection in pulse-Doppler radar based on multi-scanning signal integration The reflected signal from a target is a distorted white noise coherent packet of radio pulses with random initial phase and known amplitude. Target ... OS Neuimin,SY Zhuk - 《Bulletin of National Technical Universi...
Received expanded radar pulses pass through a surface acoustic wave (SAW) weighted filter (64) for sidelobe suppression, and then into a SAW tapped delay line (66). The pulses appear at the taps (66a,66b,66c) of the delay line (66) coarsely aligned in time, pass through individual SAW...
