| titleOfInvention | Passive synthetic aperture radiation source positioning method based on multi-view processing |
| abstract | The invention provides a passive synthetic aperture radiation source positioning method based on multi-view processing, which comprises the steps of reading/simulating a radiation source target signal received by a radar generated by an instrument, and carrying out down-conversion and demodulation on the received signal to obtain a Doppler signal of a radiation source target; aiming at the determined positioning area, according to the relation between the Doppler center frequency, the modulation frequency and the squint angle, matching filters under different squint angles are designed to obtain radiation source positioning images under different squint angles; and performing incoherent accumulation on the radiation source positioning images at different oblique angles to obtain a radiation source positioning image of the positioning area, and splicing the radiation source positioning images in different areas to obtain a high-coverage positioning image. According to the invention, the data volume is reduced through downsampling, the positioning efficiency is improved, the signal-to-noise ratio of the positioning image is improved through incoherent accumulation of the positioning images under different squint angles, and by adopting the technical scheme of the invention, the high-precision, high-resolution and high-sensitivity rapid positioning of the radiation source target is realized. |
