Frequency hopping spread spectrum (FHSS) or simply frequency hopping (FA) is a common communication method that changes the carrier frequency. Frequency hopping communication method is widely used for secure communication link due to its various benefits such as strong anti-jamming ability. As systems using frequency hopping increase, the need for detection of frequency hopping signals and parameter estimation has increased, and the development of these methods has become a critical research area in terms of security. In this study, recent studies in the field of detection and parameter estimation of frequency hopping signals are examined in two separate categories for single and multiple targets. Additionally, future research areas and challenges are discussed. Thus, future studies are guided.

Frekans atlamalı yayılı spektrum (İng. Frequency Hopping Spread Spectrum (FHSS)) ya da kısaca frekans atlamalı (FA), taşıyıcı frekansı değiştiren yaygın bir haberleşme yöntemidir. Frekans atlamalı haberleşme yöntemi, anti-karıştırma kabiliyetinin güçlü olması gibi çeşitli yararlarından dolayı güvenli iletişim bağlantısı için yaygın olarak kullanılmaktadır. Frekans atlama kullanan sistemler arttıkça, frekans atlayan sinyallerinin tespiti ve parametre kestirimine olan ihtiyaç daha da artmış ve bu yöntemlerin geliştirilmesi, güvenlik açısından kritik bir araştırma alanı haline gelmiştir. Bu çalışmada frekans atlamalı sinyalleri tespit ve parametre kestirimi alanındaki son çalışmalar tek ve çoklu hedefler için iki ayrı kategoride incelenmiştir. Ayrıca gelecek araştırma alanları ve zorlukları tartışılmıştır. Böylece gelecekteki çalışmalara yol gösterilmiştir.
