Abstract

The invention provides a method and platform for extracting and verifying characteristic parameters of infrared bell-shaped pulses, including: selecting and loading a signal template, and drawing an infrared pulse signal; setting environmental parameters according to experimental needs; and uniformly managing the signal template and environmental parameters, Generate experimental input data; extract experimental output data, and generate infrared bell pulse characteristic parameter extraction results. The present invention identifies infrared bell-shaped pulse characteristic parameters based on signal templates, can cover various targets and interference types, and ensures the complexity and diversity of test scenarios; uses a limited set to realize comprehensive verification of infrared bell-shaped pulse characteristic parameters; and through a single identification feature Standardization of parameters to achieve test standardization; realize dynamic testing without changing the software under test.

Description

technical field [0001] The invention relates to the technical field of software testing, in particular to a method and platform for extracting and verifying characteristic parameters of infrared bell pulses. Background technique [0002] Rosette Scanning Infrared Seeker (RS1S) detects the target position and collects image information by covering the entire field of view with a rose petal-like scanning trajectory in the center of the detector’s instantaneous field of view. The scanning trajectory is as follows: figure 1 shown. When the detector sweeps over the target, it generates a pulse signal. For targets with different volumes, the width of the pulse signal is different; for the same target, when it scans the edge and the center, the pulse signal has different amplitudes. Identifying the width of the pulse signal can eliminate false targets formed by white clouds reflecting sunlight with too large a pulse width and interference glitch signals in circuits with a small pu...
