Chapter 3 / Sensors / Seeker _ _ 3.9.8.3 Bearing and Elevation The target angles with respect to the Missile Body frame are the sum of the measured gimbal angles and the measured position of the target with respect to the detector boresight, ~ S ~ S ~ H ~ S ~ H ~ S ( Ψ , Θ ) : = ( Ψ + Ψ , Θ + Θ ) B B 3.9-14 B H B H Equation 3.9-24 The target angles with respect to the detector are corrupted by signal-tonoise dependent random noise, zero-mean Gaussian noise with a deviation of 2 mrad, residual radome aberration, and glint.

Chapter 3 / Sensors / Seeker _ _ The beam width for a cosine radiation pattern depends on a radiating frequency (SKλT) of 17 GHz, and the antenna diameter, 70% of the missile diameter (dm) defined in §6.3, SK ξ BW 3.9-15 : = 1. 3 ⋅ SKλ 0. 7 ⋅ d m T Equation 3.9-30 Including the antenna efficiency in with the general loss term leaves the directive gain as a function of the antenna beam-width (SKξBW) of 2°, The SNR is therefore, SK SN : = SK G : = 4 ⋅ π ξ SK 2 BW 4 SK P ⋅ ( 0. 7 ⋅ dm ) ⋅ SKt P ⋅ SKσ RCS 3 2 4 ( 4 ⋅ π ) ⋅ k ⋅ T ⋅ λ ⋅ L ⋅ P B SK S SK T SK S Equation 3.9-31 m, t Equation 3.9-32 The RCS area (SKσCSA) is set to 1.0. Assuming a sky noise temperature of 290 K, and negligible antennae to receiver input loss, the system noise temperature (SKTS) is dominated by the electronic noise factor (SKLRN), SK T : = 290⋅ S SK L RN Equation 3.9-33 Additional loss factors due to clear air atmospheric attenuation (LA) and constant signal processing loss (SKLS) are taken into consideration but not rain attenuation, clutter or multipath errors. The total loss factor, 3.9.8.5 Glint Error SK L : = S 10 0. 1 Equation 3.9-34 The glint model described in §3.8.7 is repeated for the RF seeker, the wave number and bandwidth computed at the detector and output interface rate, rS rS ( k , ω ) : = ( 2 ⋅ π ⋅ f c , 2 ⋅ l ⋅ ω ⋅ k ) SK WN SK G SK T t S, TV SK WN Equation 3.9-35 The target dimensions normal to the seeker LOS and the angular velocity of the rotating line of reflectors along the target longitudinal axis are,
