Chapter 3 / Sensors / Seeker _ _ 3.9.9 Sensor Limitiations Provision of seeker range, range-rate, bearing and elevation measurements at the output interface depends on: • User target measurement selection ( MS_MSAV2 bits 1 to 4 cleared ) • Range limiting ( SK_SD_ER bit 20 is set ) • Out-of-beam limitations ( SK_SD_ER bit 21 is set ) • Fade ( SK_SD_ER bit 22 is set ) When active, if any of these limitations are violated, bits 1-4 in the measurement ready flag MS_MSRY2 are cleared. Failure to provide measurements at the user request is indicated by setting bits 1-4 of MS_SK_VF depending on the measurements affected. Measurements are provided if the target range is within [RMIN,RMAX], defaulting to [0.1,5] km. Failure to provide measurements due to minimum or maximum limiting is indicated by setting bits 5-6 of MS_SK_VF respectively. Measurements are also suspended if the target lies outside the ± 2° beam angle (SKξBW), ξ SB S SB S SB H 3.9-17 H B B A T : = T ⋅ T ⋅ T ⋅ −1 ( ) T S T SB SB ( cos ΨS ⋅ cosΘS ) < SK BW : = cos ξ A Equation 3.9-44 Equation 3.9-45 Failure to provide measurements when the target is not in the beam is indicated by the setting of bit 7 in MS_SK_VF. If the detector is being used in strap-down mode the missile boresight to seeker head angles are zero. If the gimbals are free to rotate the angle between the detector and beam is zero. For a brief review of Swirling target models refer to §3.8.8. Failure to provide detector measurements due fade is indicated by setting bit 8 of MS_SK_VF. 3.9.10 Output Interface The unsigned range, signed range-rate and target angles are pass through a 16 bit digital interface at a frequency (SKfO) of 400 Hz (clock 9). They are subject to interface range limits of [0,5000] m, ± 5000 m/s and ± 90°, and a one-cycle transmission delay.
