Please try to answer some of the more frequently asked training
questions in written form.
In answering these questions perhaps you could print out this page.
Please respond these specific questions about radar basics. The reasonable time to frame the answers is about 30 minutes. You can use pocket calculator, but the chosen here numerical examples are optimized to perform with mental arithmetic.
- A STALO oscillate above the radar frequency band in a receiver input stage as shown in the figure.
Which frequency band must include the STALO at least?
2,7…3 GHz450 MHz75 MHz2,7…3 GHz?450 MHz75 MHz75 – 450 MHz
3,15 – 3,45 GHz
2,7 – 3,0 GHz
- Which value does the first image frequency have at the wiring example shown above
and at a operating frequency of 2.8 GHz?
- If one has got the measuring equipment for measuring the radar receiver sensitivity (MDS echo),
can one collect a receiver-calibration curve without a special measuring tool then also?
no, it technically isn't possible
yes, it is technically possible, but it’s very time-consuming
- If the band width of the echo signal is 5 MHz, which radar assemblies must possess this value at least too?
all video amplifiers
all local oscillators
