Muri sisitemu za radar, ibikoresho bipima ikirere bikoreshwa cyane cyane mu guhindura ikimenyetso cya echo cyakirwa na radar kivuye ku kimenyetso cya radio frequency (RF) kikajya mu kimenyetso cya baseband kugira ngo gikomeze gutegurwa nko gupima intera no gupima umuvuduko w'intego. By'umwihariko, ibimenyetso bya RF bipima ikirere kinini bitangwa na radar bitera imiraba itatanye ku ntego, kandi nyuma y'uko ibyo bimenyetso bya echo byakiriwe, gutunganya ibimenyetso bigomba gukorwa binyuze muri detector. Detector ihindura impinduka mu bushobozi n'inshuro bya RF bipima ikirere kinini mo DC cyangwa ibimenyetso by'amashanyarazi bipima ikirere gito kugira ngo ibimenyetso bikurikiraho bitunganywe.
Mu by’ukuri, detector ni igice cy’imikorere mu nzira yo kwakira radar, harimo cyane cyane amplifier y’ibimenyetso, mixer, local oscillator, filter na amplifier bigizwe na echo signal receiver. Muri byo, local oscillator ishobora gukoreshwa nk'isoko y’ibimenyetso (Local Oscillator, LO) kugira ngo itange ikimenyetso cyo guhuza mixer, kandi filters na amplifier bikoreshwa cyane mu gushungura buhoro buhoro imiyoboro y’amashanyarazi no kongera ikimenyetso cya IF. Kubwibyo, detector igira uruhare runini muri sisitemu ya radar, kandi imikorere yayo n’imikorere yayo bigira ingaruka zitaziguye ku bushobozi bwo kumenya no gukurikirana sisitemu ya radar.
