TI中文支持网Part Number:AWR1843
Hi, I'd like to ask you a few questions. If I have 3 radars: AWR1843. I want them to be positioned in different locations to detect the same moving target and implement a distributed multi-base radar. If each radar has different frequency band, such as 76-77GHZ for RADAR A, 78-79GHZ for radar B, and 79-80 GHZ for radar C. That way, if I work at the same time,
1. Does A radar pick up the echo signal of ABC three radars?
2. Both B and C radars will have direct waves and target echoes received by A at the same time. I would like to ask: in this case, after mixing frequency inside the radar, will radar A directly filter out the high-frequency direct wave and target reflection signal from the two radars of BC? Or will it contain echo data from all three ABC radars?
3. If each radar is a separate system, can they work in a distributed system? (Not in cascade form, I mean multi-base radar system)
4. When three radars are working at the same time, can they separate a-A, A-B, A-C, B-C, B-B and C-C signals through signal processing of received data?
5. If each channel signal can be separated, is there any way to realize the synchronization of transmitting signal and receiving signal of this distributed radar?
Please answer the engineer! Thank you very much
您好，我想教教几个问题。如果我有3部雷达：AWR1843。我想让他们放置在不同位置对同一个运动目标进行检测实现分布式多基雷达。如果每部雷达的各自频段都不同，比如A雷达76-77GHZ，B雷达78-79GHZ,C雷达79-80GHz。这样的话，如果同时工作，
- A雷达会接收到ABC三部雷达的回波信号是吗？
- BC两部雷达同时会有直达波和目标反射的回波被A接收到。我想问：这种情况下A雷达在雷达内部混频后会直接把来自BC两部雷达的高频直达波和目标反射回波信号过滤掉吗？还是同时会包含ABC三部雷达的回波数据？
- 如果每部雷达都是一个单独的系统，他们之间还能实现分布式系统的工作方式吗？（不是级联形式，我想问的是多基站雷达系统）
- 3部雷达同时工作情况下能不能通过对接收数据的信号处理将A-A，A-B，A-C，B-C，B-B，C-C这六路信号分离开呢？
- 如果能分离开各个通道信号，那么有无办法实现这种分布式雷达的发射信号同步和接收信号同步问题呢？
请工程师解答一下！万分感谢
Chris Meng：
你好，
我理解多个雷达之间如果不同步，是很难让A采集到B的信号，其他同理。而且你配置ABC三个雷达的频段是不同，他们三个之间是不会相互干扰的。

您好，
非常感谢您的回答。我还想请教几个问题：
1.如果我要实现只用一台电脑能否连接三部雷达（每部雷达+DCA）？
2.三部雷达之间实现硬件触发同时发射信号同时采集信号并捕获数据。请问我应该怎么实现呢？能否说一下具体步骤呢？需要外部的单片机吗应该怎么操作呢？
3.三部雷达捕获的数据能否保存在一台电脑上呢？
非常感谢！
