AWJ-TEST — Resilient PNT Threat Emulation — K9 Electronics Ltd

Test your CRPA against real threats

Standard CRPA test methodologies use static CW tones from a single direction. Resilient PNT demands more. AWJ-TEST is a phase-coherent multi-channel RF generator producing GNSS threat emulation waveforms that expose the true performance envelope of any CRPA or adaptive anti-jam system — dynamic nulling verification at a fraction of the cost of constellation simulators.

The Problem

Your CRPA has an untested performance gap

CRPA adaptive beamforming algorithms have well-documented vulnerabilities that standard laboratory test equipment does not stress. Convergence time windows, degrees-of-freedom limits, covariance stationarity assumptions, AGC interaction — none of these are meaningfully evaluated by static CW tone testing.

The result is a gap between published null-depth specifications and real-world resilient PNT performance. As adversaries gain access to commercial CRPA-equipped platforms, dynamic nulling verification against realistic GNSS threat emulation becomes operationally critical — not a laboratory luxury.

"Tested against a CW tone from one direction" is not resilient PNT validation. Professional-grade GNSS threat emulation and dynamic nulling verification should not require a quarter-million pound constellation simulator.

Current test methodology
Static CW tone — single direction
Algorithm converges once, holds indefinitely. No AGC stress. No degree-of-freedom exhaustion. No convergence window exploitation. Null depth figure looks excellent on a datasheet.
Operational reality
Frequency-agile, non-stationary interference
Waveforms that change faster than convergence time. Signals that appear to arrive from multiple directions simultaneously. Amplitude variation that hunts AGC circuits. The algorithm is never given a stable problem to solve.
AWJ-TEST addresses this
Intelligent algorithm stress-testing
Six distinct threat modes. Rapid programmable mode switching. Four independent phase-coherent channels. The only portable system specifically designed to expose adaptive beamforming vulnerabilities.
Capabilities

Six attack vectors. One system.

Each mode targets a distinct vulnerability in CRPA adaptive processing. Used in combination, they create compound stress that no single-mode system can replicate.

MODE 01
Non-Stationary Random
Pseudo-random frequency hops with varying dwell times and amplitude. Non-stationary statistics that prevent covariance matrix convergence and hunt AGC continuously.
MODE 02
Fast Wideband Sweep
DDS-driven frequency sweep faster than adaptive algorithm convergence windows. The null forms on where the interference was — not where it is.
MODE 03
Multi-Tone Generation
Simultaneous multiple frequency generation creating apparent spatial sources that consume null degrees-of-freedom budget. Exhausts a 4-element CRPA's nulling capacity from a single transmitter.
MODE 04
Chirp / Linear Ramp
Linear frequency ramp generating Doppler-like signatures that confuse direction-of-arrival estimators. Particularly effective against STAP and SFAP algorithm implementations.
MODE 05
Burst / Amplitude Pulsing
Sub-millisecond on/off amplitude patterns creating AGC hunting transients during which beamforming weight calculations are corrupted. Effective null depth degradation without power increase.
MODE 06
Programmable Mode Switching
Rapid switching between modes at intervals shorter than CRPA convergence time. Contrast-scored transition matrix ensures consecutive modes are maximally statistically distinct — the algorithm is always reconverging, never stabilising.

Why AWJ-TEST

Three reasons organisations choose AWJ-TEST

The Democratiser
Professional-grade CRPA testing shouldn't cost a quarter-million pounds
Validate your resilient PNT designs against realistic GNSS threat emulation for £15,000. The same phase-coherent multi-channel RF generation capability as laboratory systems — at a price that puts one on every engineer's bench.
The Field Kit
Don't bring the platform to the lab. Bring the lab to the platform.
Portable GNSS jamming emulation for real-world integration testing. AWJ-TEST is a portable alternative to anechoic chamber testing — conduct dynamic nulling verification at your test range, on your vehicle, on your platform, without laboratory infrastructure.
The Agile Developer
Shorten your dev cycles with a phase-coherent signal source at every bench
Give every algorithm developer their own GNSS threat emulator. Iterate on adaptive beamforming code against realistic non-stationary waveforms without booking shared test facilities. AWJ-TEST pays for itself in the first development sprint.
