AEROSENTRA / ACOUSTIC MOBILE
VEHICLE-MOUNTED VIP PROTECTION
ACOUSTIC-FIRST DETECTION / AUTOMATIC SENSOR CUEING

Hear the threat first.
Keep the team informed.

A mobile security platform installed on a protection vehicle. Five synchronized acoustic sensing nodes detect and classify drone-like threats, estimate their bearing, cue short-range radar and PTZ or EO/IR systems, manage multiple targets and deliver actionable alerts to the vehicle crew and command center.

Protection must move with the principal

Fixed-site systems protect a location. AeroSentra Acoustic Mobile protects a moving security formation. The system is designed for executive protection vehicles, official convoys, arrival and departure zones, temporary secure areas and mobile command operations. It continues detecting, prioritizing and recording events while the vehicle is stationary or in motion.

An acoustic detector supported by verification sensors

The acoustic subsystem is the primary detector. Radar and optical systems receive its cue, verify the candidate, improve range and trajectory information and maintain visual tracking. The operator receives one fused target picture instead of separate sensor alarms.

PRIMARY DETECTION

Five acoustic sensing nodes

Distributed microphone-array nodes provide 360-degree coverage, synchronized sampling, bearing estimation and resilience if one node becomes unavailable.

SIGNATURE ANALYSIS

Acoustic classification

Time-frequency processing separates drone-like rotor signatures from vehicle, road, wind and other environmental noise, then assigns confidence and quality values.

RANGE AND MOTION

Short-range radar verification

Radar examines the acoustically indicated sector and contributes range, radial speed, trajectory and time-to-arrival data to the fused track.

VISUAL VERIFICATION

PTZ or EO/IR cueing

One or two stabilized optical units automatically turn toward the acoustic bearing, scan the uncertainty sector, confirm the target and maintain day or night tracking.

FUSED TARGET PICTURE

Multi-sensor correlation

Time, bearing, range, motion and optical observations are associated with one persistent target ID and one combined confidence score.

MOTION COMPENSATION

GNSS and IMU reference

Vehicle position, heading, speed and attitude convert acoustic bearings into a stable geographic frame while compensating for turns, vibration and road movement.

One clear operating principle

EVENT ORIGIN

Acoustic detection opens the threat event

The system creates a threat candidate only after the acoustic engine detects a relevant signature and produces a valid bearing, confidence and signal-quality result.

  • Acoustic timestamp becomes the event reference
  • Acoustic bearing defines the first search sector
  • Repeated detections maintain track continuity
  • Every event preserves the original acoustic evidence
SUPPORTING SENSORS

Radar and optics verify, refine and follow

Supporting sensors do not create an independent system alarm. They receive an acoustic cue and enrich the existing target with additional operational information.

  • Radar adds range, speed and trajectory
  • PTZ or EO/IR adds visual confirmation
  • Fusion increases or reduces target confidence
  • Tracking continues through temporary sensor loss

From acoustic signature to operational alert

The detection chain is automatic, traceable and designed to minimize operator workload during a moving protection mission.

Listen

Five synchronized nodes continuously capture the acoustic environment around the vehicle.

Detect

The engine identifies a relevant signature across time, frequency and several nodes.

Locate

Time-delay processing estimates bearing and converts it to vehicle and geographic coordinates.

Verify

Radar and PTZ or EO/IR are directed to the candidate sector and return supporting evidence.

Prioritize

Fusion evaluates confidence, closing speed, direction and proximity to the protected formation.

Alert

The crew and control room receive one track, live status, evidence and recommended attention level.

Every alert carries the operational payload

The alert payload contains the acoustic source information, vehicle reference, supporting radar and optical verification, target priority, evidence files and system health. This enables rapid review in the vehicle and complete event handling in the control room.

Manage several acoustic threats at the same time

Every valid signature receives a persistent track ID. The target manager separates bearings, correlates repeated observations and allocates radar and optical resources according to threat priority.
