I've thought about space warfare and seen how sensor information has been displayed in various Science Fiction franchises and been left disappointed.
For our future space forces we need screens which (after some training) intuitively provide critical tactical information to the officers of a future space warship. Some information is obvious (distance, velocity, acceleration, position in X-Y-Z [or radial] coordinates, etc.), but
How do I display this and make it relevant to the officers of our ship?
When would I need one sort of display versus another?
For example,
When in deep space one useful sensor plot not seen in current era (naval) vessels would be the time to important distances as magnitude and expected close approach direction shown as direction plot using logarithmic scale and spherical coordinates. "Important distances" may include any or all of the following:
- Effective weapon range for light speed weapons, missiles, torpedoes, projectiles.
- Intercepts with other vessels or "space terrain" (like planets, moons, or asteroids).
In deep space, Navigation may desire a plot showing required $\Delta$V shown as magnitude and thrust vector shown as direction. Depending upon the available $\Delta$V, this might also require a logarithmic scale (or not).
When your vessel and "nearby" objects are all in orbit near a planet/moon, a more conventional range as magnitude and orientation as direction in a spherical coordinate system centered on the planet/moon might work.
Then again, the system described in #1 above would also work (how long until the bogey is in range and in which direction from the ship will that encounter occur).
Two other things to consider,
- When considering things that require $\Delta$V to be effective (ships, shuttles, missiles, etc.) the specifics (distance, direction, velocity vector, acceleration vector, etc.) of the encounter are important (How to add tactics to space warfare). In a stern chase scenario, the ship being chased has a much longer effective range for missile weaponry (the missile's effective acceleration and $\Delta$V are boosted by the acceleration and $\Delta$V of the chasing ship). So range or velocity plots should show a significant skew in their circles of effective range.
- At long ranges, plots showing the location and $\Delta$V of objects shouldn't show precise data for other objects under acceleration. They should show baskets of likely data. The basket shows a probability that the other object will be in that part of the basket. The basket shows the other object's acceleration ability to foil intercept or weapons calculations. CJ Cherryh's "Down Below Station" describes this very well.
