Choosing a UAV Detection Module: Three Parameter Groups Integrators Should Read First

The Module-Sourcing Question

Counter-UAS manufacturers face the same trade-off repeatedly: detection performance sets the ceiling of the product, yet developing an RF detection chain in-house often runs past the project budget. The CH-M1 UAV detection and positioning module takes a different route — detection, decoding and Remote ID identification are packaged into a single module that exposes its capabilities through a standard interface.

What Modularity Actually Removes: Interface Boundaries, Not Steps

The CH-M1 technical documentation states the design intent plainly: standard interface design simplifies hardware design and reduces software development complexity. The integrator's engineering effort therefore shifts away from RF and demodulation and toward enclosure design, power supply and upper-layer software. On the RF side the module provides 300M–6G omnidirectional and directional antenna ports plus a 2.4/5.8G dual-band port. On the data side it offers S5/S7 serial ports that can also serve as general I/O, two USB ports and one Gigabit Ethernet port. On the software side it supports HTTP data push to third parties and provides an API.

Three Parameter Groups to Read First

The first is sensitivity. Detection sensitivity is -105 dBm, decoding sensitivity is -100 dBm and RID sensitivity is -90 dBm, all specified at 10 MHz bandwidth. The three figures are not equal because they belong to different demodulation chains — hearing a signal is not the same as reading it. During evaluation, confirm which level your target set actually depends on rather than comparing only the lowest number.

The second is size and weight. The module measures 150 * 80 * 37 mm and weighs 470 ± 5 g. A weight difference at module level is amplified at product level, and these two figures determine whether it can be embedded in handheld, vehicle-mounted or backpack platforms without consuming structural margin.

The third is power and environment. The operating temperature range is -20 to 60 °C. Supply voltage is specified at DC 15~36V; for the confirmed input range of a specific configuration, contact us before finalising the power design. Wide voltage input reduces the need for an additional regulation stage, while the temperature range sets the boundary for long-term outdoor operation.

Three Items to Verify Before Integration

First, the open interface set. RF interfaces 4 and 5 are listed as Reserved and unused, so confirm that your required functions fall inside the interfaces already exposed. Second, the preconditions behind the data. The documentation notes that positioning data is derived from decoding, that locatable targets are DJI series models using OcuSync image transmission, and that the capabilities apply to modular embedded platforms. Third, the upgrade path. The module supports online remote upgrade of the system version.

Summary

The value of a UAV detection module is not that it replaces enclosure design, but that it converts the technical risk of the RF detection stage into interfaces and parameters that can be checked. For integrators, confirming sensitivity tiers, size and weight, and power and environment boundaries first — then verifying interface availability and data preconditions — is more efficient than comparing finished-product specifications.
