NOTE: This is an ugly planet, a bug planet...these should be treated as very rough approximations.
NOTE II: An important point to be made for BMD radars is that they work both ways -- you can track your own outbound missile trajectories for "quality", i.e. are your ICBMs following their programmed trajectories, or will their RV's miss their target by "x" amount?

Apogee 525 seconds in, @ 648 km alt and 1361.2 km downrange
Impact 1020 seconds @ 2778 km downrange
2780 km Thor IRBM Trajectory: 650~ km apogee, 17 min (1020s) flight time.
10,000 km "Lofted" Trajectory: 2300 km Apogee, 42 min (2520s) flight time, 35 deg re-entry
10,000 km "Min-Energy" Trajectory: 1200 km Apogee, 31 min (1860s) flight time, 23 deg re-entry
10,000 km "Depressed" Trajectory: 900 km Apogee, 28 min (1680s) flight time, 15 deg re-entry
LGM-30B Minuteman I Maximum Range Trajectory: 10,186 km, 1640 km Apogee, 37.5 min (2250s) flight time For Early ICBMs, to shorten the range; you increased Apogee (and flight time)
SS-6 SAPWOOD (R-7A): 325-sec burn time
SS-18 SATAN / SS-25 (RT-2PM Topol): 300-sec burn time
SS-11 Mod 1 SEGO (UR-100): 260-sec burn time
Minuteman I: 180-sec burn time
Thor IRBM: 160-sec burn time
Kinetic Energy Interceptor: 60-sec burn time
The stock sensor values for detection ranges are "eyeball" guesses against a "Standard" target, the Mk 12 RV [181 cm long, 54 cm base diameter, 0.005 m2 RCS at 4300 - 153 MHz at 0 degree aspect (head-on)].
Multipliers to adjust sensor values for differing targets/aspects are:
NOTE: The stock sensor values are for rough "detect+track" S/N Ratios of 20. If you want extremely high quality discrimination (S/N 200) values, divide the stock values by 1.78
Red Line: Outside of FOV/Range for Sensor. Green Line: Within of FOV+Range for Sensor. Orange Circle: Burnout Point (Approx.) Blue Circle: Apogee (Approx.)
Pink Shading: Specified range covered from selected launch point.
