however, in an easing of the electrical requirements. With a proportional 

 navigation system such as is often used in missile guidance, the actual bore- 

 sight error is not of consequence compared with the rate of change of 

 apparent error with respect to angle.'** Practical limits for this rate of 

 change of radome error are nearly ±0.05° per degree.
