2957 specifications

The Elta 2957 is a premier ground-based radar system designed to provide comprehensive surveillance capabilities for airspace management and security operations. Its sophisticated technology sets it apart as an essential tool for military and civilian applications alike.

One of the main features of the Elta 2957 is its advanced Active Electronically Scanned Array (AESA) technology. This innovative radar system uses a phased array, allowing it to electronically steer the beam of energy without moving parts. This capability ensures rapid target acquisition and tracking, significantly enhancing situational awareness in dynamic environments. The AESA technology also allows for simultaneous multi-target tracking, making it an invaluable asset for monitoring multiple aerial threats.

The Elta 2957 operates in the S-band frequency range, which provides an optimal balance between range and resolution. This frequency choice allows the radar to detect a variety of airborne objects, including small UAVs, combat aircraft, and incoming missiles, ensuring versatile applications across different operational theaters. Its high resolution offers a detailed view of the operational landscape, enabling decision-makers to respond effectively to potential threats.

In terms of characteristics, the Elta 2957 boasts a high level of resistance to electronic countermeasures. Its capabilities are further enhanced by sophisticated signal processing algorithms that filter out noise, ensuring that operators receive clear and actionable data. This resilience against jamming is crucial for maintaining operational integrity in conflict scenarios.

The system is designed for ease of integration into existing command and control infrastructures. Its modular architecture facilitates upgrades and compatibility with other defense systems, ensuring long-term usability as technologies evolve. Furthermore, the radar is mobile, allowing for rapid deployment and reconfiguration in response to emerging threats.

With its combination of advanced technologies, high-resolution performance, and robust operational features, the Elta 2957 stands out as a leading solution in the realm of ground-based radar systems. It serves as a critical asset for nations seeking to enhance their airspace security and situational awareness, paving the way for superior defense operations in an increasingly complex aerial environment.
