A baseband tracking channel in a GNSS receiver is provided. The baseband tracking channel comprises: a code generator to generate a local signal correlating with an incoming signal received by the GNSS receiver; a multiplier that multiplies the local signal with a baseband signal corresponding to an incoming signal received by the GNSS receiver to generate a code removed signal; a prompt correlator including at least one integration register that integrates samples of the code removed signal corresponding to a first portion of each pseudorandom noise code chip of the code removed signal to provide a first integration register output, and integrates samples corresponding to a second portion of each PRN code chip to provide a second integration register output; and a side peak tracking detection module that generates information indicating when side peak tracking is occurring based on the first integration register output and the second integration register output.

A system for detecting a target object includes a first detector that detects an object by emitting radio waves and receiving reflected waves that are the emitted radio waves reflected by a target object, a second detector that detects heat generated by the target object, and an information collection apparatus that determines the presence or absence of the target object on the basis of the detected reflected waves and the detected heat, and the information collection apparatus determines the presence of the target object in a case where the first detector has detected a movement of the target object and the second detector has detected the heat.

Provided are a method and vector computing unit for implementing de-scrambling and de-spreading, and a computer storage medium. The method includes that: an operation of complex multiplication on baseband data and corresponding de-scrambling and de-spreading codes is performed by adopting data transformation and addition, and data obtained by the complex multiplication is stored into a vector register file; a row of data obtained by the complex multiplication is read from the vector register file, every two adjacent pieces of data in the row of data are accumulated to obtain a half row of data, a row of data, and finally one piece of accumulated data; and the accumulation processing is continued on other rows of data to implement accumulation of each row of data obtained by the complex multiplication in the vector register file.
