[TEC] How much was radar affected by bad weather?

[LukeFF]

Bulleye, you're right. The way radar is modeled right now depicts doppler radar, which only picks up moving objects; pulse radar, which gives a return on both stationary and moving objects, was the standard during the war.

Now, the reason I ask about fog affecting radar is this page I found at hnsa.org:

FACTORS AFFECTING RADAR RANGE

Maximum range factors. In order to give you some reason for the variation in range performance of radar sets, we shall list the factors affecting the maximum range of any radar:
1. Wave length.
a. Long wave length radar is best suited for air search.
b. Micro wave length radar is best suited for surface search.
2. Size of target.
3. Height of target.
a. Height of mast for surface target.
b. Height of plane for air target.
4. Target presentation (target angle).
5. Material of target.
6. Height of antenna.
7. Output power radar.
8. Sensitivity of receiver.
9. Atmospheric condition.
10. Type of indicator ("A" scope most sensitive).
11. Pulse repetition rate (determines maximum range scale that can be used).
12. Beam concentration.
13. Condition of radar equipment.
14. Operator's technique and skill.

Of interest is item 9. Is fog considered an "atmospheric condition" that can affect the range and reliability of pulse radar?

Here is another comment from that manual:

Remember that for all practical purposes radar is not affected by visual limitations. It can detect equally well through darkness and smoke, and almost as well through fog. (empahsis added)

I think I'm going to try a value of 0.2 and see how that affects things.
