IAI Integrates Naval Combat Suite on Sa’ar 6 Corvettes

Israel Aerospace Industries (IAI), together with the Administration for the Development of Weapons and Technological Infrastructure (part of IMoD) and the Israeli Navy, completed the first phase of installing the MF-STAR (Magen Adir) radars on the Israeli Navy’s ‘Sa’ar 6’ corvettes.The next stage will be the  egration of the BARAK MX Air Defense System (Ra’am Adir) on the vessels. The radars will serve to locate and classify air and surface targets and help to build an advanced and detailed maritime picture of the surveillance area. The MF-STAR radar system will serve as the “brain” of the Israeli Navy’s new warships. It is also an important component of the BARAK Air Defense System.

ELTA’s MF-STAR (ELM-2248) is a digital AESA (Active Electronic Scanning Array) multi-function radar. It employs multi-beam and pulse Doppler techniques as well as Electronic counter-countermeasures (ECCM) techniques to extract low Radar cross-section (RCS) targets from complex clutter and jamming environments. The Transmit/Receive element digital output enables software only adaptive beam forming and mode variations to form a software defined radar. The MF-STAR antenna includes 4 scalable faces of active arrays in S-Band frequency. These 4 faces can be installed in various configurations and in different sizes.

Upon identifying a threat, the radar supplies all required data immediately to each control, defense and support systems on deck, enabling to respond in real-time. The BARAK MX Air Defense System provides both wide-area and targeted defense capabilities to an array of threats, including: land, air and sea. The system aggregates several key cutting-edge systems: a digital radar, weapon control system, launchers, a range of interceptors for different ranges with advanced homing devices, data-link communication and system wide connectivity.

IAI Unveiled a Passive Radar

ELTA Systems, a subsidiary of Israel Aerospace Industries Group, unveiled this week a new Passive Coherent Location Radar System, enables the creation of an air situation using non-cooperative transmitters. It detects and tracks aerial threats based on target reflection from FM or Digital Audio Broadcasting (DAB) towers. The reflections are received by one or a network of antennas, providing 3D real-time tracking of multiple targets in congested airborne traffic.

The PCL system installation can include one sensor or a cluster of sensors for redundancy and improved coverage. The sites are connected to the central PCL command and control processing unit via a dedicated data link. General Manager of ELTA Intelligence, Communications and EW division, Adi Dulberg, said that the PCL system detects and classifies aerial risks, “without unveiling the locator.”

Very small footprint

Passive coherent location systems (sometimes called ‘Passive Radar’) systems are a variant of Bistatic Radar in which the reciever and the transmitter are separate. But the PCL variant does not employ any transmitter at all – it exploit ‘existing illuminators’ as their sources of radar transmission. These sources can be analogue FM radio, cellular phone base stations, digital audio broadcast (DAB) and other sources.

Passive radar systems offer several key benefits. They are hard to detect by conventional means: Electronic sensors cannot pick them up because they do not transmit their own signals. They have no transmitters generating heat, so they cannot be detected thermal signatures, and they are small and quite difficult to spot. According to Visiongain rtesearch firm, the global passive radar market is projected to grow from US$ 2,324 million in 2020 to US$ 4,313 million by 2030, at a CAGR of 6.38% between 2020 and 2030.

 

Needed a Radar to distinguish between Humans and Animals

The Directorate of Defense Research & Development in The Israeli Ministry of Defense (“Mafat”) announced its new competition, MAFAT Radar Challenge, for the development of capability to accurately distinguish between humans and animals in radar tracks? The winner will receive $40,000. The competition’s objective is to explore automated, novel solutions that will enable classification for humans and animals with a high degree of confidence and accuracy.

While some object types are easily distinguishable from one another by traditional signal processing techniques, distinguishing between humans and animals, which are non-rigid objects, tracked in doppler-pulse radars, is a difficult task. Today, the task of classifying radar-tracked, non-rigid objects is mostly done by human operators and requires the integration of radar and optical systems.

Why is this a difficult task?

Classification of radar-tracked objects is traditionally done by using well-studied radar signal features. For example, the Doppler effect (Doppler shift) and the radar cross-section (RCS) of an object can be utilized for the classification task, however, from the radar system’s perspective, looking at the tracked objects through the lens of those traditional features, humans and animals appear very similar.

Microwave signals travel at the speed of light but still obey the Doppler effect. Microwave radars receive a Doppler frequency shifted reflection from a moving object. Frequency is shifted higher for approaching objects and lower for receding objects. The Doppler effect is a strong feature for some classification tasks, such as separating moving vehicles from animals. However, humans and animals are typically moving at the same range of velocities.

The radar cross-section (RCS) is a measure of how detectable an object is by radar. An object reflects a limited amount of radar energy back to the source, and this reflected energy is used to calculate the RCS of an object. A larger RCS indicates that an object is more easily detected by radars. Multiple factors contribute to the RCS of an object, including its size, material, shape, orientation, and more.

The RCS is a classic feature for classifying tracked objects. However, it turns out that the RCS of humans is similar to the RCS of many animals; thus, RCS alone is not a good enough separating feature as well. The task of automatically distinguishing between humans and animals based on their radar signature is, therefore, a challenging task.

The objective of the competition is to explore whether creative approaches and techniques, including deep convolutional neural networks, recurrent neural networks, transformers, classical machine learning, classical signal processing, and more, can provide better solutions for this difficult task.

Mafat is interested in approaches that are inspired by non-radar fields, including computer vision, audio analysis, sequential data analysis, and so on. It provides real-world data (I/Q Matrix), gathered from diverse geographical locations, different times, sensors, and qualities (high- and low-signal to noise ratio—SNR). The competitor’s mission is to identify whether the segment of the tracked object is an animal or a human.
