Embodiment Construction
[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific preferred embodiments.
[0033] Such as figure 1 As shown in Fig. 1 , a track association method of echo fusion target based on track state estimation includes the following steps.
[0034] Step 1, sector division in polar coordinates: divide the radar video data in polar coordinates into several sectors at equal distances and azimuths, preferably 48*24 sectors, wherein there are 24 azimuth sectors in total, each Each sector is 15°. Then, the execution of the target tracking module is driven by sectors, preferably azimuth sectors (track update).
[0035] Step 2, track start or update: build a new target track with the target echoes that meet the track start conditions, and form a new target track. The initial state of the track is a non-fusion state, such as figure 2 shown.
[0036] The above-mentioned target echoes that meet the track start co...
