Abstract

The invention belongs to the field of radar target echo simulation of radar simulation test equipment, and specifically relates to a pulse compression radar dense target simulation method based on frequency-domain matched filtering. Through a dense target real-time simulation method, a standard multi-target signal can be generated flexibly with fewer device logic resources to test the multi-target detection resolution precision of radar, a flaky clutter target signal based on dense targets can be generated in a simulated manner to detect the anti-clutter detection ability of radar in signal processing, and a smart noise jamming signal based on dense targets can be generated in a simulated manner to detect the anti-smart-noise-jamming ability of radar in signal processing.

Description

Technical field The invention belongs to the field of radar target echo simulation of radar simulation test equipment, and specifically relates to a pulse compression radar dense target simulation method based on frequency domain matching filtering. Background technique With the rapid development of modern radar technology, the design of radar waveforms is becoming more and more complex. Various technologies such as frequency agility, nonlinear frequency modulation, phase encoding, and large bandwidth are used to design waveforms to obtain better target search, tracking and anti-jamming , Anti-stealth performance. The consequent difficulty in the design, development, debugging, and detection of radar systems has become greater. If only relying on field tests, it would take a huge amount of manpower, material resources and time to meet the requirements of the complex electronic countermeasure environment of modern warfare. The development of modern radar system simulation tech...
