Much of intercept decision making rests with…….

First launch opportunity (FLO) is the lesser of……

Role of Radar SAM in IADS….
Track target and guide missile to intercept
Active homing guidance
A seeker onboard the missile tracks the target
Semiactive radar (SAR) homing guidance
Missile homes in on the energy reflected off the target
Command guidance
The ground radar provide the missile steering commands
Two combined guidance schemes
Track via missile (TVM): combines both command and SAR guidance- target and missile tracked by TTR
Internal guidance (GAI): combines command and INS hardware on missile - only target is tracked by TTR
What are the 3 missile guidance laws
Command LOS
Half rectified
Pro-Navigation (most effective)
Describe 3 types of command LOS guidance
Manual: operator directly steers the missile
Semi auto: operator keeps optics crosshairs on target, system tracks missile and sends commands
Auto: systems tracks target and missile
Describe Half rectified intercept and how would that appear in the canopy
A missile is guided to a point halfway between the target position and the predicted intercept point
Missile drifts aft slowly in the canopy
What is pro-navigation
Most efficient trajectory; as long as LOS remains less than 90 degrees, intercept will happen
IR SAMS, MANPADS
Define Minimum intercept range
The min range a missile can guide and successfully fuze on a target.
Define maximum recommended intercept range (MRIR)
The max range the system was designed to intercept a target
