BREAKING NEWS
The ALPER Naval LPI Radar is engineered primarily for surface warfare (ASuW), littoral operations, and close-range maritime domain awareness. Its core mission is the detection and tracking of small surface contacts, asymmetric maritime threats, and low-altitude airborne targets in complex sea environments.
Operational Purpose and Role
Modern naval operations increasingly occur in congested littoral waters where small, fast-moving threats and low-observable targets pose significant risks. ALPER is optimized to address these challenges by providing:
Its LPI characteristic enhances survivability in electronic warfare-heavy environments.
Doctrine and Concept of Use
ALPER is typically integrated on:
Within the ship’s sensor suite, it contributes to the overall tactical picture and feeds data to the combat management system (CMS). The sector blanking feature allows selective emission control in specific azimuth sectors, reducing electromagnetic exposure toward known enemy ESM directions. Alarm sector definition enables rapid operator response to threats emerging from predefined bearings.
System Architecture
The ALPER radar system consists of:
Operating in X-Band with an FMCW (Frequency Modulated Continuous Wave) waveform, the radar continuously transmits low-power signals, enabling precise range and velocity measurement.
Compared to conventional pulse radars, FMCW technology provides:
Survivability and Electronic Warfare Resilience
The radar’s transmission power is less than 1 watt, significantly reducing detectability by hostile electronic support measures (ESM). This contributes to:
Compliance with MIL-STD-810F and MIL-STD-461E ensures environmental robustness and electromagnetic compatibility under harsh maritime conditions.
Advantages Against Modern Threats
As an X-Band tactical surveillance radar, its role is optimized for short-to-medium range detection rather than long-range area air defense.
