“Static Human Detection” is the watershed separating advanced smart sensing from basic motion detection. Shenzhen StarCore Technology Co., Ltd.'s XKC-LD002, powered by 60G mmWave Bio-Radar Technology, sets a new benchmark for reliability.Deep Dive: From Physics to Algorithms1. Physical Layer Advantage (60G mmWave):
Short Wavelength: ~5mm wavelength is exquisitely sensitive to micro-movements, detecting millimeter-scale displacements.
Fine Doppler Resolution: Highly responsive to the tiny Doppler shifts caused by periodic chest movement (breathing, 0.1-0.5Hz) and heart pulsations (~1Hz).
Low Noise Floor: This frequency band has minimal environmental clutter and strong immunity to common EMI.
2. Algorithmic Breakthrough (Bio-Radar Processing):Raw mmWave return signals are complex. The XKC-LD002's proprietary algorithm executes key steps:
Clutter Suppression: Filters out static reflections from walls and furniture.
Vital Sign Extraction: Uses time-frequency analysis (e.g., STFT) and pattern recognition to isolate respiration and heartbeat harmonics—the signatures of life.
Presence Logic: Continuous detection of valid vital signs triggers an “Occupied” state. Absence of signals beyond a threshold triggers “Vacant.”
Proven Performance:In a standard office desk scenario, the XKC-LD002 achieves a static presence detection rate >99% with a false-positive rate <1%. This is the core reason it is replacing PIR as the gold standard in high-end automation.Shenzhen StarCore Tech: Solving core challenges with core technology.
