A multispectral camouflage net is only as good as the requirement it was bought against. Two nets that look identical on a table can perform very differently against the sensors that actually matter — and the difference rarely shows up until it is too late. This checklist walks through the questions a defence buyer should settle before issuing a specification, so that bids can be compared on the same basis and the delivered system matches the threat. It states no product performance figures; it is a guide to asking the right questions.
TL;DR
- Start from the threat: list the sensors the net must defeat before listing any material property.
- Specify every band that matters — visible, near-infrared, SWIR, and thermal — not just the ones that are easy to test.
- Match the net to the real operating environment and to the platforms it will cover.
- Demand performance after realistic ageing, not just on the day of delivery, backed by independent test evidence.
- Account for size, weight, deployment time, and lifecycle cost, not only signature performance.
Step 1 — Define the threat sensors
Every other decision flows from this one. Before any material property is written down, list the sensors the net is actually meant to defeat: the human eye and optics, image-intensifier night-vision devices working in the near-infrared, short-wave infrared cameras, thermal imagers in the long-wave band, and radar. A net optimised against one sensor can be transparent to another, so a vague ‘multispectral’ requirement that does not name the threat is impossible to bid against fairly.
Step 2 — Specify the bands explicitly
Translate the threat list into named bands, and state the expected behaviour in each:
- Visible. Colour and disruptive pattern matched to the background.
- Near-infrared. Reflectance matched so the net does not betray itself under night-vision devices.
- SWIR. Where short-wave infrared sensors are part of the threat, ask for matching across that band too.
- Thermal. Managed emissivity and break-up in the long-wave infrared band.
- Radar. If radar is a concern, state whether scattering or attenuation is required, and over which frequencies.
If you are unsure what ‘multispectral’ should cover for your mission, our complete guide to multi-spectral camouflage walks through each band in turn.
Step 3 — Match the environment and platform
A net tuned for temperate woodland will not match desert or snow. Specify the operating environment(s), and decide whether you need a reversible net to handle more than one. State the platforms to be covered — vehicles, guns, shelters, radars — because shape, drape, and ventilation requirements differ. Note any need to operate communications or sensors through the net, which constrains the radar specification.
Step 4 — Demand performance after ageing
The most common procurement trap is specifying performance only as delivered. Field service exposes a net to ultraviolet light, abrasion, moisture, temperature extremes, and repeated deployment. Ask for the signature match and the mechanical properties to be retained after a defined ageing regime, and for flame-retardancy and other safety properties to be stated. A net that meets its numbers new but fades within a season is a false economy.
Step 5 — Require independent test evidence
Insist that claims be backed by measurement at an accredited laboratory, with the method and conditions stated, so that bids can be compared on the same basis. Our explainer on NABL certification describes what accredited testing means in the Indian context. Treat a single headline figure with no stated method with caution; reproducible, independently measured results across the specified bands are the evidence that matters.
Step 6 — Account for logistics and lifecycle
Signature performance is necessary but not sufficient. Specify size and modularity, weight (which drives how quickly a team can deploy and recover the net), packed volume, deployment and recovery time, repairability, and expected service life. The lowest unit price is rarely the lowest lifecycle cost once handling, durability, and replacement are taken into account.
A one-page checklist
Pulling the six steps together, a complete multispectral net specification answers:
- Which sensors must it defeat?
- Which bands are named, and what is required in each?
- Which environments and platforms must it match?
- What performance is required after ageing, and to what safety properties?
- What independent test evidence is required, against which methods?
- What size, weight, deployment, and lifecycle constraints apply?
Settle these before going to market and the bids will be comparable and the delivered net fit for the threat. For help turning a mission into a defensible specification, contact our team.
Frequently Asked Questions
How do I write a specification for a multispectral camouflage net?
Start from the threat sensors the net must defeat, translate them into named bands (visible, near-infrared, SWIR, thermal, radar) with required behaviour in each, match the net to the operating environment and platforms, and demand performance after ageing backed by independent test evidence — then add size, weight, deployment, and lifecycle requirements.
Which bands should a multispectral net cover?
At minimum the visible and near-infrared bands; increasingly SWIR and the thermal (long-wave infrared) band; and radar where that is part of the threat. Name only the bands your threat sensors actually use, but do not omit ones simply because they are harder to test.
Why specify performance after ageing?
Because field service exposes a net to ultraviolet light, abrasion, moisture, and temperature extremes. A net that meets its numbers when new but degrades within a season is a false economy, so the specification should require performance to be retained after a defined ageing regime.
What test evidence should I ask for?
Measurement at an accredited laboratory, with the method and conditions stated, across each specified band. Reproducible, independently measured results are far stronger evidence than a single headline figure with no stated method.
Should I choose a reversible net?
A reversible net is useful when one system must match more than one environment, such as woodland on one side and a more arid or snowy palette on the other. If your operations span distinct backgrounds, specify reversibility; if not, a single-sided net may suffice.
Is the cheapest net the best value?
Not usually. The lowest unit price often carries higher lifecycle cost once durability, handling, deployment time, repairability, and replacement are considered. Evaluate value over the service life, not at the point of purchase.

Detection systems across the spectrum
Modern detection is multi-spectral: electro-optical targeting such as Sniper ATP and LITENING in the visible band; image-intensified night vision and 1064 nm laser designation in the near-infrared; infrared search-and-track such as OLS-35 and PIRATE and imaging-IR seekers such as AIM-9X and Javelin across the thermal bands; and AESA fire-control radars such as the AN/APG-81 in the radar band. CAMPRO multi-spectral systems are engineered to suppress a signature across this full sensor stack. This guide is educational and states no product performance figures.
