STRUCT RADAR_DETECTOR_SPECS(9)

👑 struct radar_detector_specs(9) 👑

okay so bestie, welcome to the Kernel API Manual ✨ — this is the page for struct radar_detector_specs, and it is literally the blueprint for one radar pattern type's detector specs. no cap, if you're doing DFS/radar detection stuff on wifi, this struct is your main character. 🎀

🌸 NAME 🌸

struct radar_detector_specs — detector specs for a radar pattern type 💅

---

✨ SYNOPSIS ✨

struct radar_detector_specs {
    u8 type_id;
    u8 width_min;
    u8 width_max;
    u16 pri_min;
    u16 pri_max;
    u8 num_pri;
    u8 ppb;
    u8 ppb_thresh;
    u8 max_pri_tolerance;
    bool chirp;
 };

like… look at her. she's tiny. she's iconic. she holds the whole vibe check for one radar pattern type 🦋

okay now the important part — every single field, no skipping, i would never do that to you 🫶

• type_id — the pattern type, as defined by regulatory. the official ID of the radar vibe, iykyk 🎀
• width_min — minimum radar pulse width in [us] ⏱️
• width_max — maximum radar pulse width in [us] ⏱️
• pri_min — minimum pulse repetition interval in [us] (including tolerance) 🔥
• pri_max — minimum pri in [us] (including tolerance) 🙈 — yeah, the page literally says "minimum" for pri_max here. that's what it says, i'm not out here fixing it, i'm just reporting it 💀
• num_pri — maximum number of different pri for this type, so like… how many pri options she can hold 👑
• ppb — pulses per bursts for this type 💥
• ppb_thresh — number of pulses required to trigger detection. this is the "how many taps before it goes off" number 🍓
• max_pri_tolerance — pulse time stamp tolerance on both sides [us]. both sides! generous queen 🌈
• chirp — chirp required for the radar pattern 🐦

ok bestie go read those too, the friend group is literally all connected 💜

and that's the whole page!! mwah 💋 — this masterpiece lives over in ./drivers/net/wireless/ath, dated October 2026, and it's struct radar_detector_specs(9) forever and always. periodt. 👑✨
