Agat shows 'world's smallest' active-radar missile seeker

Doug Richardson

At the June 2005 Paris Air Show, the Moscow-based Agat Research Institute displayed a prototype of what it believes is the world's smallest active-radar missile seeker, writes Doug Richardson. Designed in a diameter that seems to rule out a Russian application, it may be intended for use on Chinese missiles.

A derivative of the organisation's earlier 9B-1103M seeker, the new 9B-1103M-150 has a diameter of only 150 mm and a total weight of about 8 kg. (The original 9B-1103M is 200 mm in diameter and weighs 14.5 kg.)

The new seeker is designed for use in short-range missiles currently guided by infrared (IR) seekers, Agat Director and General Designer Joseph Akopian told JMR. Such missiles use seekers mounted behind hemispherical windows of less-than-ideal aerodynamic form. Fitting the missile with an active-radar seeker will provide all-weather capability and allow the use of a more aerodynamic nose profile radome whose reduced drag can improve the weapon's kinematic performance and provide a greater maximum range.

The nose radome was almost certainly developed by the 'Technologiya' State Research Centre. This organisation specialises in radome technology (see JMR June 2005, p15), and, according to Akopian, has developed the radomes for all the Agat seekers.

Like the 9B-1103M, the new seeker is fully digital. Few details have been released, but it is known to offer the same search, lock-on and tracking capabilities as the larger seeker, passing homing data to the missile's control system via a digital link. The original 9B-1103M can operate in a fully autonomous 'fire-and-forget' mode and its onboard computer can be reprogrammed to match the changing circumstances of the engagement.

Since the performance of any active-radar sensor is related to the aperture size (area) of the antenna, the reduction in antenna diameter that results from the smaller antenna of the 9M-1103M-150 inevitably means that the maximum lock-on range of the new seeker is less than that of the larger 9M-1103M. Against a target of 5 m2 radar cross-section, the new seeker has a maximum lock-on range of 13 km, while the larger 200 mm-diameter seeker can manage lock-on at up to 20 km range against a similar target.

Three prototypes of the 9B-1103M-150 have been built, said Akopian. These have been extensively tested in the laboratory and in Agat's hardware-in-the-loop (HWIL) facility. There are no plans for carry trials on an aircraft; flight testing would not begin until a customer can be found.

When Hughes (now part of Raytheon) developed the active-radar seeker of the AIM-120 Advanced Medium-Range Air-to-Air Missile (AMRAAM) in the 1980s, the company described the task as having involved cramming an air-to-air radar capability similar to that of the AN/APG-66 radar of the F-16 Fighting Falcon into a seven-inch (178 mm)-diameter fuselage. In the subsequent two decades, few design teams have faced the challenge of developing smaller active-radar seekers.

During the late 1980s, Thompson-CSF (now Thales) fitted an active-radar seeker into the 165 mm-diameter fuselage of the Matra (now MBDA) MICA (Missile d' Interception et de Combat Aerien). Currently, the smallest active-radar seeker in service on an air-to-air missile is the Israeli Aircraft Industries unit fitted to the Rafael Derby and its South African equivalent, the R-Darter, which have a diameter of 160 mm.

India's Astra missile uses a 178 mm fuselage, while other missiles with active-radar seekers have a diameter of about 200 mm - for example, the Tien Chien II (190 mm), the Mitsubishi Type 99 (200 mm) and China's SD-10/PL-12 (203 mm). The forward fuselage of the R-27A and R-27EA active-radar variants of Vympel's AA-10 'Alamo' inherited the 230 mm diameter of the earlier semi-active radar and IR-guided variants.

A single-page leaflet released by Agat describes the potential applications of the 9B-1103M-150 seeker as being "air-to-air and air-to-surface missiles". In practice, however, there are no Russian IR-guided air-to-air or air-to-surface weapons of about 150 mm diameter. The only obvious candidate for the new Agat seeker would be the 170 mm-diameter Vympel R-73 (AA-12 'Archer'), but if this were the intended application, it might have been more practical to have sized the new seeker to fit the fuselage of the Vympel weapon rather than squeeze it into a 150 mm package.

Foreign missiles seem more likely applications. While it may be safe to assume that MBDA is not looking for a Russian seeker for its 165 mm-diameter MICA, and Israel has already created its own active-radar guided equivalent of the 160 mm Python, China might be a market for a radar version of its China National Aero Technology Import & Export Corporation (CATIC) PL-8 Python 'look-alike'.

Fitting an active-radar seeker to the PL-8 would give China a missile in the same performance class as the Derby and R-Darter. At around 120 kg, it would be substantially lighter than China's current PL-12/SD-10, which weighs 180 kg. Derby and R-Darter are small enough to be carried on light fighters such as the F-5, so an active-radar PL-8 variant could find a useful role in modernising China's large force of F-7 fighters, or as an alternative armament for the new FC-1 fighter.

Several missiles use 157 mm-diameter fuselages, including the Matra R.550 Magic 1 and 2, and Denel's Darter series, but another application for the Agat seeker might be CATIC's 157 mm-diameter PL-7 and PL-9.

In Brazil, the Mectron-Engenharia/Centro Tecnico Aeroespacial MAA-1 Piranha has only just completed development, so this 152 mm-diameter missile is unlikely to be a potential application for an active-radar seeker, at least in the short term.

In the case of IR-guided surface-to-air missiles, there is no potential Russian application for the 9B-1103M-150 seeker. The missiles used in the KB Tochmash 9K31 Strela-1 (SA-9 'Gaskin') and 9K35 Strela-10 (SA-13 'Gopher') systems are both 12 cm in diameter. However, China has used the PL-9 as the basis for a short-range surface-to-air missile system, and has offered the surface-launched PL-8 as part of a combined missile/gun naval air-defence system.
