Real-World Notes on Phased Array Radar

I’ve spent more than a decade talking to integrators, pilots, and procurement teams. The consensus? When you need fast, silent beam steering without a spinning dish, a Phased Array Radar from Longgang District, Shenzhen, is increasingly the go-to. It synthesizes a high-gain electronic beam using phase differences across many T/R modules—search and tracking in milliseconds, not seconds. And yes, to be honest, the leap in GaN power devices over the past five years is the real story here.

Industry Trends (what buyers actually ask about)

• GaN AESA: higher EIRP with better thermal headroom; real-world range improves ≈15–30%.
• Digital beamforming + low-sidelobe tapers for urban clutter—especially important for counter‑UAS.
• SWaP pressure: modular tiles for drones, vehicles, and compact fixed sites.
• Software-first roadmaps: waveform agility, FMCW+pulse hybrids, and open APIs (Ethernet/Time Sync).

Product Snapshot

How it’s built and tested

Materials: GaN MMIC T/R modules on copper coin heat spreaders, Rogers/low-loss laminates, CNC’d aluminum chassis, conformal coating.

Methods: tile-level phase calibration, built-in self-test, adaptive beamforming, and clutter maps. Environmental sealing for coastal installs.

Testing standards: MIL‑STD‑810H (vibe/thermal), MIL‑STD‑461G (EMC), IEC 60529 (IP rating), and chamber-measured patterns per IEEE radar definitions.

Service life: 10–15 years with periodic fan/filter swaps; MTBF modeled >50,000 h at 35°C ambient.

Industries: counter‑UAS, perimeter security, maritime, weather micro‑cells, smart highways, and research labs.

Application snapshots

• Urban drone defense: fast beam hopping tracks low‑RCS targets near buildings. One city client said detection “stopped being guesswork.”
• Harbor surveillance: 24/7 rain clutter rejection; integration with AIS and EO/IR for confirmation.

Vendor landscape (quick take)

Customization & integration

Options include band selection, TRM count, scan rate, waveform library (pulse, LFM, FMCW), and SDK hooks. Many customers say the open REST/Protobuf API saves a sprint or two. It seems that edge AI trackers on the same box reduce handoff latency to cameras.

Sample test data (lab + field)

• EIRP: ≈74 dBm at X‑band, 10% duty (chamber).
• 2° × 2° beam, −26 dB sidelobes (pattern mask pass).
• RCS 0.05 m² drone tracked to 4.2 km (urban ridge test, humid 30°C).

Origin: Longgang District, Shenzhen. Warranty and support through local partners; spares kit recommended for 24/7 sites.
