Embodiment Construction

[0031] The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.

[0032] Such as figure 1 As shown, the present invention proposes an improved ship track logic initial algorithm, which specifically includes the following steps:

[0033] Step 1: Classify and judge the situation of missing points in the temporary track

[0034] Taking the first frame of the radar scanning as the track head, a batch of new temporary tracks are established, and the lost points of the subsequent measurement points are classified and judged in several radar scanning cycles, and the false targets of interference are eliminated.

[0035] If within the 10-frame cumulative scanning period of the radar, a...

Abstract

The invention discloses a ship track logic initiation algorithm. The ship track logic initiation algorithm comprises steps that temporary track losing point classification discrimination, distance changing rule statistic discrimination, maneuverability analysis discrimination, namely suppression discrimination of continuous N-shaped false track having course deviation greater than or equal to 90 degrees and target speed, course, acceleration fluctuation discrimination are established by radar scanning. The ship track logic initiation algorithm is advantageous in that under a condition of severe clutter environment, by combining various track initiation rules, an initiation false alarm rate of a false target is reduced, and real target track initiation accuracy is improved, and therefore subsequent target stability tracking is facilitated, and probabilities of false track wrong following and real track losing are reduced.

Description

technical field [0001] The invention belongs to the field of radar data processing, and in particular relates to an improved ship track logic initial algorithm. Background technique [0002] From the level of radar measurement data processing, if the radar signal processing is regarded as the first processing, then the radar data processing is the reprocessing after the radar signal processing. The content of radar data processing is very extensive, mainly to perform interconnection, tracking, filtering, smoothing, prediction and other processing on the radar measurement data, accurately estimate the target position and related motion parameters, such as speed, acceleration, etc., and predict the position of the target at the next moment. And form a stable target track to achieve high-precision real-time tracking of the target. Track initiation is the first step of target tracking and the primary problem of track processing. It mainly includes two aspects: temporary track e...
