RFPA-keystone transform: A search-free coherent integration method for random frequency and PRI agile radar

Key Points

• Enhanced coherent integration allows for better performance in agile radar systems, particularly with varying pulse repetition intervals (PRI).
• Key results indicate that the RFPA-keystone transform can manage random frequency signals effectively, showing a notable decrease in search time.
• The study utilizes a novel transform method, improving conventional radar signal processing techniques.
• This method could significantly enhance radar applications in dynamic environments, addressing the limitations of previous approaches.
