Description
Data Sheet

Radar PCB is a specialized high-frequency substrate tailored for radar electronic equipment, commonly deployed in communication radar, detection radar, and millimeter-wave radar systems. Currently, millimeter-wave radar applied in automotive ADAS has maintained rapid iterative development and large-scale commercial adoption.

Radar equipment requires high-performance high-frequency PCB materials with precisely controlled dielectric constant (DK) and dissipation factor (DF) throughout manufacturing. Maxipcb selects high-frequency base materials with a DK range of 2 to 16 for radar PCB mass production, covering PTFE Teflon substrate, ceramic substrate and hydrocarbon composite substrate to satisfy diverse high-frequency and microwave working conditions.

Radar operates by transmitting electromagnetic waves via antennas. After reflecting off target obstacles, the echoed signals are captured and analyzed. By calculating the propagation time of electromagnetic waves, radar achieves accurate measurement of target distance, position and moving speed. A complete primary radar system comprises four core units: a transmitter for electromagnetic wave generation, an antenna for signal radiation and echo reception, a receiver for weak signal amplification, and a display module for target information presentation. When electromagnetic waves hit a target, diffused reflection occurs in all directions. The antenna collects backscattered signals and transmits data to the receiver, which identifies target characteristics and calculates spatial parameters. Featuring all-weather, high-precision detection capability, radar is widely applied in military defense, aviation, marine navigation, meteorological observation and other key fields.

Radar Classification

Radar products are divided into military and civil grades. Air defense radar is used for searching, monitoring and identifying aerial targets, including early warning radar, guidance radar and low-altitude detection radar. Marine warning radar is mainly installed on ships, coastal and island facilities to monitor surface targets.

By functional attributes: Early warning radar, guidance radar, fire control radar, altitude measurement radar, blind landing radar, terrain matching radar, imaging radar, meteorological radar, etc.

By working system: Conical scanning radar, monopulse radar, passive/active phased array radar, pulse compression radar, frequency agile radar, synthetic aperture radar, multi-static radar, beyond visual range radar and other types.

By working wavelength: Meter-wave, decimeter-wave, centimeter-wave, millimeter-wave and infrared lidar.

By measurement parameters: Two-coordinate radar, three-coordinate radar, velocity measurement radar, altitude measurement radar and guidance radar.

Phased Array Radar Principle

The antenna array of phased array radar consists of hundreds to tens of thousands of regularly arranged radiation and receiving units. The quantity of array units is determined by radar functional requirements. Combined with electromagnetic wave coherence theory, computer-controlled phase shifters adjust the current phase of each unit to realize beam electronic scanning without mechanical rotation. Each antenna unit is equipped with phase regulators to produce directional radiation beams. More array units deliver higher scanning precision and multi-angle spatial detection capability.

Phased array radar is categorized into Passive Electronically Scanned Array (PESA) and Active Electronically Scanned Array (AESA). PESA technology is mature and cost-efficient, widely equipped on vessels and medium-sized aircraft since the 1980s. AESA features superior comprehensive performance and technical expandability, and has been widely applied to advanced fighter jets and shipborne systems since the late 1990s.

Modern warfare and civil detection scenarios rely heavily on phased array radar and high-precision positioning technology. Related ranging systems include missile test ranges, space launch sites and conventional weapon test bases, covering long-distance monitoring, orbit tracking and target characteristic identification.

Radar PCB Design Difficulties

Radar PCB integrates digital signals, analog circuits and microwave RF modules, bringing high complexity to board layout and routing design, especially for hybrid assembly of RF and low-frequency components. Circuit boards with operating frequencies above 1GHz are classified as high-frequency radar PCBs, which need to withstand stable transmission of microwave high-frequency signals.

RF radar PCB design faces multiple technical bottlenecks. Cross-team design with inconsistent file formats reduces R&D efficiency. Frequent structural adjustments are required for RF circuit matching. Isolated RF simulation fails to take overall board electromagnetic interference into account, resulting in actual performance deviation. In addition, data conversion between RF simulation software and PCB design tools (such as DXF file adaptation) is prone to parsing errors. Manual modification easily causes dimensional deviation, which further leads to RF circuit failure and unstable mass production quality.

Importance of Professional Radar PCB Manufacturers

Radar PCB is extremely sensitive to electromagnetic interference, impedance fluctuation and signal noise. Qualified manufacturers adopt standardized production processes to control all interference factors and ensure long-term stable operation of high-frequency circuits. Inferior boards are prone to signal attenuation, aging damage and performance failure in complex high-frequency environments, making professional high-frequency PCB suppliers a key factor for radar product reliability.
