Radar Miss Distance Indicator RM-100

The miss distance indicator is a Pulse Doppler Radar scalar MDI. The radar miss distance indicator uses the radio wave emitted by the target and the echo reflected from the missile to obtain the miss range when the target attacks the target, so as to provide the basis for the evaluation of shooting effect.

1 Application scenario 
Missile and target missile design verification, identification and finalization, production approval and equipment training range test.

2 Product advantage
    2.1 The system adopts the wide-beam gazing system, and the transceiver antenna of the radar directly covers the hemisphere-space, avoiding the switching of antenna beam, and ensuring the reliable detection and acceptance of the echo signal of high-speed attack targets in any direction. In all the live missions, the targets within the measurement range were successfully detected and recruited.
    2.2 Pulsed Doppler radar system is adopted. Compared with continuous wave radar system, it requires less spacing between transceiver antennas, and there is no need to separate transmitting and receiving antennas by a relatively large distance. It can also easily achieve high transmitter-receiving isolation when installed on target aircraft or target missile platform with limited space. In addition, pulse Doppler radar has range resolution, which can suppress the influence of ground clutter and sea clutter.
     2.3 Using advanced high-speed real-time signal processing architecture and target detection and tracking algorithm, the constant false alarm detection can be carried out on the high-speed moving target in the strong sea-ground clutter environment where the rendezvous time of missile and target (target missile) lasts only 1-2 seconds, and the range gate where it is located can be tracked in real time, from which the high-precision Doppler frequency history information of target echo can be extracted. Furthermore, the results of miss distance measurement are obtained.
    2.4 High technology maturity and wide application. With the technology of the invention, four generations of Type 7 equipment have been developed successively, which have been used in the test identification and training of various missile development and equipment at various firing ranges.
