And the calculation efficiency of the device is greatly improved.

Description

technical field [0001] The invention relates to the technical field of electronic signal passive detection, in particular to a geographical grid voting device based on OpenVPX architecture. Background technique [0002] Spaceborne electronic signal detection is an important means to achieve target detection and surface electromagnetic environment monitoring by passively receiving electromagnetic signals emitted by radiation sources such as radars and analyzing their electromagnetic parameters and position information. Spaceborne electronic signal detection covers a wide range, and the number of radar emitter signal pulses acquired at the same time is very large. How to realize radar emitter pulse signal sorting and emitter location, separate each emitter pulse signal and obtain its position information is particularly important. [0003] In order to solve the above problems, in the related art, the pulse signal sorting and positioning of the radar radiation source are realiz...
