Advanced active radar seeker 9B-1103M (diameter 350)

Active radar seeker 9B-1103M upgraded prototype (diameter 350 mm) is designed to complete the units of air-to-air and surface-to-air missiles.

Purpose: to fit air-to-air and surface-to-air missiles.

Provides:
- search, lock-on and tracking of moving targets upon target designation from airborne and air defense radars:
-measuring of target angular coordinates, angular rates and missile-to-target closing speed;
- generation and transfer of signals measured to missile control system.
Operating modes:
- active (“fire-and-forget”) completely autonomous mode using only preliminary target designation data, without any external radar support during flight;
- inertial guidance with updating.

Specifications:
1. Composition:
- controlled coordinator with antenna;
- transmitting channel hardware;
- receiving channel hardware;
- reprogrammed on-board digital computing system in composition of control computer and signal processor.
2. Type of guidance system:
- inertial guidance with updating and active homing;
3. Lock-on range of targets with RCS = 5m2   : 40 km, no less;
4. Speed of on-board digital computing system  : 50106 op/s, no less;
5. Time ready (after preliminary warm-up for 2 min) : 1.0 sec;
6. Mass (less radome)      : 13 kg, no more;
7. Diameter        : 350 mm;
8. Length (less radome)      : 310 mm.

Collaboration supposes initiation of ordered or joint R-effort on the basis of Advanced seeker 9B-1103M with follow-on as R&D efforts.
